3 * Added silc_hash_table_del[_by_context]_ext functions in to the
4 lib/silcutil/silchashtable.[ch].
6 Removed silc_hash_table_find_all* routines and added new
7 silc_hash_table_find_foreach to replace them.
9 Added silc_hash_table_replace_ext function as extended
10 replacing function. Separated the simple hash table interface
11 from the extended hash table interface in the file
12 lib/silcutil/silchashtable.h.
14 * Fixed minor bugs and changed it to use some of the new
15 hash table functions in lib/silccore/idcache.c
17 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Added new function silc_hash_table_find_all to return all keys
20 in the hash table by the specified key. As the hash table is
21 collision resistant it also makes it possible to have several
22 duplicate keys in the hash table. This function may be used to
23 find all of the keys from the hash.
25 Added user_context arguments to the SilcHashFunction,
26 SilcHashCompare and SilcHashDestructor to deliver user specified
29 Added new fuctions silc_hash_table_find[_all]_ext to do
30 extended lookup with specified hash and compare functions and
31 specified user contexts.
33 Added new function silc_hash_table_add_ext to add the key
34 with specified hash function and user context.
36 Added new function silc_hash_table_foreach to traverse all
37 entrys in the hash table. Added SilcHashForeach callback
40 Added new function silc_hash_table_del_by_context to delete
41 the entry only if the context associated with the key matches.
43 Affected files are lib/silcutil/silchashtable.[ch].
45 * Removed silc_hash_[server/client/channel]_id and added just
46 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
47 silc_hash_id_compare to compare two ID's using as the hash table
48 comparison function. Added also silc_hash_data to hash
49 binary data and silc_hash_data_compare to compare it.
51 * Removed silc_idlist_find_client_by_hash as it is not needed
52 anymore. Affected file silcd/idlist.[ch].
54 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
55 to use internally the SilcHashTable. The new ID Cache is a lot
56 faster than the old one. Some of the ID Cache interface was also
57 rewritten and obsolete and stupid functions were removed.
59 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Added entry_count field to the SilcHashTable to keep the number
62 of the entries in the table. Implemented the function
63 silc_hash_table_rehash. Added new function
64 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
66 Fixed a minor bug in silc_hash_table_free.
68 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
69 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
70 into the lib/silcutil/silcutil.[ch].
72 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Implemented a collision resistant hash table into the
75 lib/silcutil/silchashtable[ch]. See the header and the source
76 for the SilcHashTable API.
78 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Merged dotconf version 1.0.2 into lib/dotconf.
82 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
84 * Do not compile anything in lib/silcsim/* if the SIM support
85 is not enabled. The tree should now compile without problems
88 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Compiled the SILC under cygwin. Compiled and tested briefly
91 without problems. More tests needed. The SIMs didn't compile
94 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
96 * Fixed possible crash in silc_get_username in the
97 lib/silcutil/silcutil.c.
99 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Fixed a va_arg in silc/client_ops.c.
103 * Oops, RC5 routines were named AES and caused some problems
104 when not using SIM's. Affected file lib/silccrypt/rc5.c.
106 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added new SilcIDIP structure into the lib/silccore/id.h and
109 replaced the old `ip' fields from all SILC ID's to that type.
110 This is a step towards IPv6 support.
112 The silc_id_get_len takes now the ID as an extra argument.
113 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
114 both IPv4 and IPv6 based ID's.
116 The affected files are lib/silccore/id.[ch] and other files
117 around the tree using these routines.
119 * Removed the ID length arguments in server from various
120 silc_server_send_notify_* routines -> they are not needed
123 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
125 * Fixed memory leak in silc_encode_pem_file in the file
126 lib/silcutil/silcutil.c.
128 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Check minor version as well in the SKE. Affected files are
131 silcd/protocol.c and lib/silcclient/protocol.c.
133 * Added --identifier option to the server so that an identifier
134 can be when creating the public key for the server. Affected
135 file is silcd/silcd.c.
137 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
138 lib/silccrypt/silcpkcs.c.
140 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * Register default ciphers and stuff when using -C option with
143 the server. Affected file sildc/silcd.c.
145 * Put back the servers public key filename format, it is better
146 than the new one. For now, the client keys are saved with the
147 new filename format. The affected file silc/client_ops.c.
149 * Implemented the Cipher API for the rest of the ciphers that
150 did not implement it or implemented it the wrong way.
152 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Register default ciphers and stuff when using the -S option
155 in the client. Affected file silc/silc.c. Same also when
156 creating new key pair with -C option.
158 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
160 * Fixed the silc_verify_public_key client operation function to
161 save the public keys differently. The fingerprint is now
162 used as filename and not the hostname. This way also the
163 client keys are saved uniquely and not with hostnames. The
164 affected file is silc/client_ops.c.
166 * Trimmed the silc_hash_fingerprint function to remove extra
167 whitespaces from the end of the fingerprint. The affected
168 file is lib/silccrypt/silchash.c.
172 * Added silc_cipher_register_default function to register all
173 default ciphers. It can be used when configuration files
174 does not exist and the application does not want any specific
175 ciphers in any specific order.
177 The SilcDList is now used as silc_cipher_list dynamically
178 allocated cipher list. Removed the static list all together
179 and now all ciphers must be allocated to the dynamic list.
180 The silc_cipher_alloc routine was changed to check only the
183 All silc_cipher_* routines that used to return int returns
186 The affected files lib/silccrypt/silccrypt.[ch].
188 * The same thing was done to silc_hash_* as for silc_cipher_*
189 routines. Affected files lib/silccrypt/silchash.[ch].
191 * The same thing was done to silc_pkcs_* as for silc_cipher_*
192 routines. Affected files lib/silccrypt/silcpkcs.[ch].
193 Added also silc_pkcs_[un]register[_default] functions.
194 Removed the data_context from the PKCS API.
196 * Added silc_hmac_register_default function to register default
197 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
198 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
199 to unregister all hmacs at once.
201 * Register the default ciphers, hash functions, PKCSs and HMACs
202 if client's configuration file does not exist. The affected
205 * The client did not load the hash functions from the SIM
206 modules at all. Added support for this. Affected file is
209 * When decoding public key with silc_pkcs_public_key_decode, check
210 the supported algorithm only if PKCS are registered. Affected
211 file lib/silccrypt/silcpkcs.c. The same was done with the
212 silc_pkcs_private_key_decode.
214 * Fixed the SILC List routines to keep the list always in order.
215 It used to change the list's order when traversing the list but
216 not it preserves the order. Affected file lib/trq/silclist.h.
218 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
220 * Added the client library to use the SilcSocketConnection's
221 reference counter (by silc_socket_dup) to prevent the bug that
222 the socket object may be freed underneath async operation.
224 * The name resolv library checking fixes in the configure.in.pre.
227 * Created new version of the protocol drafts for future
228 development. The -03 drafts are the ones that will be changed
229 in the trunk now and the -02 will remain as they are.
231 * Send list of CUMODE notifys to the router when announcing
232 the channel users to the router. Affected file silcd/server.c.
233 If the router receiving channel founder CUMODE for a channel
234 that already has channel founder it will send CUMODE notify
235 to the sender to remove the channel founder rights from the
236 announced client. Affected file silcd/packet_receive.c.
238 * The CUMODE notify may now use Server ID as well as the entity
239 who changes the mode. Updated protocool specs.
241 * Updated INSTALL and README files.
243 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * New web pages in the http://silc.pspt.fi. The pages was
250 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
252 * Implemented the [DenyConnectin] config section in the server.
253 Added silc_server_config_denied_conn to check whether incoming
254 connection is denied. Affected file silcd/serverconfig.[ch].
256 * Do not check the ports when checking the incoming configuration
257 data if the port is 0, meaning any. Affected file is
258 silcd/serverconfig.c.
260 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed buffer overflow in silc_string_compare in the file
263 lib/silcutil/silcutil.c.
265 * Fixed double free in silc_server_command_leave in the file
268 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Fixed the version checking in the server. Affected file is
273 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Fixed the configuration data fetching when accepting new
276 connections in the server. Affected file silcd/server.c.
278 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Added `sender_entry' argument to the function
281 silc_server_packet_relay_to_channel so that we can check
282 whether some destination actually belongs to the same route
283 the sender belongs (ie, we must not resend the packet to the
284 sender). Affected file silcd/packet_send.[ch].
286 * Added `servername' field to the SilcClientEntry in the server
287 to hold the name of the server where client is from. Affected
288 file is silcd/idlist.h.
290 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Moved the channel message encrypting in the router betwen
293 router connections from silc_server_channel_message to the
294 silc_server_packet_relay_to_channel since we want to check
295 whether we have anybody channel before encrypting anything.
296 Affected files silcd/packet_[receive/send].c.
298 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Fixed the [AdminConnection] server config section to support
301 multiple entries. Affected file silcd/serverconfig.c.
303 * Added support into the server to check the validity of the
304 incoming connection before executing any KE or authentication
307 * The connection configuration is now saved to the KE and
308 connection auth protocol contexts and not fetched anymore in
309 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
311 * The local hosts listenning address and port is also resolved
312 now when starting the server. We want to have the socket object
313 to include the real address and port for the listener. Added
314 new function silc_net_check_local_by_sock into the files
315 lib/silcutil/silcnet.[ch].
317 * Fixed a broadcast bug in server -> do not broadcast if we
320 * Fixed a routing bug. Do not route broadcast packets ever.
321 Broadcast packets must be processed always and not routed since
322 they may be destined to some other host than yourself and thus
323 would get routed without no good reason. Affected file is
326 * Added function silc_server_config_is_primary_route to check
327 whether primary router connection has been configured (a router
328 configuration that we are initiating). If there is not, we
329 will assume that there is only two routers in the SILC network
330 and we will use the incoming router connection as our primary
331 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
333 * Changed the order of the broadcasting. Broadcast _after_ the
334 packet has been processed not before. Affected file is
337 * Fixed a [ClientConnection] parsing bug. The port was never
338 parsed correctly thus resulting to port 0. Affected file
339 silcd/serverconfig.c.
341 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
342 argument and did not set the broadcast packet flag. Affected
343 file silcd/packet_send.c. Fixed same bug in the function
344 silc_server_send_notify as well.
346 * If we receive NEW_ID packet for our own ID in the server, ignore
349 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Removed the nickname from the Private Message Payload.
354 Updated the code and the protocol specs.
356 * Updated protocol specs for submitting to the IETF.
358 * Tweaked the Random Number Generator a bit. Affected file
359 lib/silccrypt/silcrng.c. Exported a new function
360 silc_rng_[global]_add_noise which can be used to add more
363 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
365 * Do not parse packets with different timeout when protocol
366 is active -> may cause problem with rekey. Affected file
369 * When server receives signoff notify it must not create
370 new channel key if the client is on any channels since the
371 sender of the signoff notify will create it.
373 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added printing of error messages during SKE protocol from the
376 failure packet sent by server during SKE. Affected file
379 * Removed the client's failure_callback handling with timeout
380 and handle it immediately when received.
382 * The SKE library returned wrong type in SUCCESS and FAILURE
383 packets. They must be 32 bit MSB not 16 bit MSB.
385 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
387 * Ok, rewrote the logic of the re-key and now it seems to work.
388 I tested it on high traffic with frequent re-keys without
389 problems. Added hmac_receive (and renamed hmac to hmac_send)
390 in SilcClientConnection in lib/silcclient/client.h and
391 in SilcIDListData in silcd/idlist.h. Also, removed the
392 SilcPacketParserContext's cipher and hmac fields as they are
393 not needed anymore and actually caused some problems when
394 the ciphers and hmac's changed underneath the packet parser.
396 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * If re-key protocol is active then process the incoming packets
399 synchronously since we must assure that icoming packets encrypted
400 with the old key is processed before the new keys is set to
401 use. This is true other packets than for REKEY packets.
402 Affected file silcd/server.c. The same was done to client library
403 as well, affected file lib/silcclient/client.c.
405 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Fixed bug in client and server to accept the force send if
408 the packet is send from silc_[server/client]_packet_process
409 function. Otherwise the packets are never delivered, oops.
411 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Disable force sending of packets when REKEY protocol is active.
414 We must assure that no packet is sent directly when rekey is
415 performed. All packets must be sent through packet queue.
416 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
417 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
418 function is silc_[server/client]_packet_send_real to check
421 * Replaced the SIM paths from example config files to
422 /usr/local/modules. Also, make install creates now
423 /usr/local/silc/logs directory to hold all the SILC server
426 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Made the configure.in.pre work on Solaris. Patch by salo.
430 * Made all ciphers compatible with non-x86 machines. Defined
431 CBC mode macros into lib/silccrypt/ciphers_def.h.
433 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Fixed the make install.
437 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * When MAC computation fails the silc_packet_decrypt returned 0
440 even though it was supposed to return -1. Fixed this. The
441 affected file is lib/silccore/silcpacket.c.
443 * Do not replace the config files in /etc/silc (in make install)
444 if they already exist. Affected file ./Makefile.am.
446 * Do not send re-key packets immediately but through packet queue.
447 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
449 * Changed silc_net_check_host_by_sock to return FALSE if the
450 IP/DNS could not be resolved. Though, it returns the IP address
451 now even if it could not resolve it (but returns also FALSE).
452 Affected file lib/silcutil/silcnet.[ch].
454 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Added silc_pkcs_decode_identifier to decode the public key's
457 identifier. Affected file lib/silccrypt/silpkcs.[ch].
458 Added also silc_pkcs_free_identifier. Added also new context
459 SilcPublicKeyIdentifier.
461 * Added -S option to the silc client. It is used to dump the
462 contents of the specified public key file.
464 * Changed the PKCS api to return the public key length when
465 setting the public key.
467 * Fixed a fatal bug in the public and private key file loading.
468 Affected file lib/silccrypt/silcpkcs.c.
470 * Execute the packet parsing for client with zero (0) timeout
471 if the protocol is active. Affected file silcd/server.c.
473 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Made the key generation options to the silcd program. Added
476 -C option, equivalent to client's option.
478 * Added new [ServerKeys] config section to the server. It
479 configures the server's public and private key.
481 * Defined generic Public Key Payload into the protocol
482 specification to send specific type of public keys and
485 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
486 public key or certificate.
488 * Implemented the GETKEY command to the server and to the
489 client library and on user interface.
491 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Made preliminary `make install' work.
495 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Added SilcServerRekey context into silcd/idlist.h.
499 * Added the PFS support as defined in the specification to the
500 SKE protocol. Affected files lib/silcske/*.c.

503 the number of the SKE group that is used with PFS in re-key.
504 Affected file silcd/idlist.h.
506 * Added PFS re-key support to the server. Affected file is
509 * Added silc_protocol_cancel to cancel execution of the next
510 state of the protocol. Affected file is
511 lib/silccore/silcprotocol.[ch].
513 * Added the re-key support with and without PFS to the client
514 library. Re-key is performed once in an hour, by default.
516 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
517 Added silc_client_rekey_callback and silc_client_rekey_final.
518 Affected files are lib/silcclient/protocol.[ch] and
519 lib/silcclient/client.[ch].
521 * Removed the `hmac_key' and `hmac_key_len' fields from the
522 SilcClientConnection structure; not needed. Affected file is
523 lib/silcclient/client.h.
527 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Do not ask whether user wants to use the negotiated private key
530 for private messages, just use it. Affected file is
531 silc/local_command.c.
533 * Added `send_enc_key' and `enc_key_len' fields to the
534 SilcIDListData structure since they are needed in the re-key
535 phase. Affected file is silcd/idlist.[ch].
537 * Implemented the simple re-key protocol into the server.
538 Affected files silcd/server.c and silcd/protocol.[ch]. The
539 re-key will be performed once in an hour, by default.

552 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
555 int64 of at least the xintXX size. If void * is less that 4
556 bytes uint32 * will be used. Defined bool as boolean.
558 * Changed _ALL_ unsigned long and unsigned int to uint32,
559 unsgined short to uint16 in the source tree.
561 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
562 not handle clients that has entry->data.registered == FALSE.
563 They are not in the network anymore. Affected file is
566 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Implemented the sending of the SERVER_SIGNOFF notify in the
569 server. Affected file is silcd/server.c.
571 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
572 Added also silc_notify_payload_encode_args into the
573 lib/silccore/silcnotify.[ch].
575 * Implemented ther SERVER_SIGNOFF notify handling in the server.
576 Affected file silcd/packet_receive.c.
578 * Implemented the SERVER_SIGNOFF notify handling in the client
579 library. Affected file lib/silcclient/client_notify.c. Also,
580 implemnted the printing of the SERVER_SIGNOFF info to the
581 application. Affected file silc/client_ops.c.
583 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
584 if the deleting was successful. Affected file silcd/idlist.[ch].
586 * Added support for public key authentication in the connection
587 authentication protocol in the client library. Affected file
588 lib/silcclient/protocol.c.
590 * Changed the server's silc_idlist_get_clients_by_* interface
591 to support already allocated array so that new entries may be
592 added to pre-allocated array. Affected file silcd/idlist.[ch].
593 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
596 * All command reply functions in the server now calls the
597 pending command callback even if error occured. This way the
598 error will be delivered to the client as well. Affected files
599 silcd/command.c and silcd/command_reply.c.
601 * Fixed INFO command to return local server's info if no server
602 was provided. Affected file lib/silcclient/command.c.
604 * Removed RESTART command for good. Updated the code and the
607 * Rewrote parts of the task system. It is a bit simpler now.
608 Removed unsued task priorities. The affected files are
609 lib/silcutil/silctask.[ch].
611 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
613 * Moved the USERS printing from the library to the application.
614 Affected files lib/silcclient/command.c and silc/client_ops.c.
616 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Added channel key re-key support. The re-key is perfomed
621 only by the router and is done once in an hour. Added `rekey'
622 field to the SilcChannelEntry in the server. Affected files
623 silcd/server.c and silcd/idlist.h.
625 * Added silc_task_unregister_by_context into the file
626 lib/silcutil/silctask.[ch].
628 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Added SILC_UMODE_GONE mode to indicate when the client is not
631 present in the SILC network. Added also support to the local
632 command AWAY that will set this mode. Added support of showing
633 "xxx is gone" in WHOIS command. The USERS command shows the
636 * Fixed setting server and router operator privileges in the
637 server's UMODE command. Affected file silcd/command.c.
639 * Merged the SKE KE1 and KE2 payloads into one payload. The
640 new KE payload is equivalent to the old KE2 payload.
642 Cleaned up the SKE Start Payload parsing. It now uses the
643 simple buffer unformatting to do the parsing. A lot faster
646 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
647 to the SKE that is used to indicate whether both of the SKE
648 parties should perform authentication. By default only the
649 responder performs authentication. By setting this flag also
650 the initiator must do authentication. By default it is unset
651 since in normal SKE case, client to server connection, only
652 the responder should do authentication. When doing SKE between
653 two clients both should perform authentication. Updated the
654 code and the protocol specs.
656 * A little fix to IDENTIFY command in the server. Search the
657 client first by hash not nickname. Affected file is
660 * Fixed the silc_client_close_connection to support closing
661 the client to client connections wihtout deleting too much
662 data. Affected file lib/silcclient/client.c.
664 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
665 are received if protocol used to be active but is not anymore
666 the application would crash due to NULL pointer dereference.
667 Affected files silcd/server.c and lib/silcclient/client.c.
669 * Added `hash' field to the SilcClientConnection to include
670 the hash function negotiated in the SKE protocol.
672 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
673 to set the channel founder authentication data. A client can
674 claim the founder rights later by providing the authentication
675 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
676 This way the channel founder can regain the channel founder
677 privileges even it is left the channel. This works only on
678 local server and the client must be connected to the same
679 server to be able to regain the founder rights. Updated the
680 protocol specs accordingly.
682 Added support to the CMODE command in the client to set the
683 founder auth data. Read the README to see how to set it.
685 Added support to the CUMODE command to claim the founder
686 rights. Read the README to see how to do it.
688 Added support for the founder authentication to the Channel
689 Entry in the server. Affected file silcd/idlist.h.
691 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
692 server's CMODE command. Affected file silcd/command.c.
694 * Added the following new functions into lib/silccore/silcauth.[ch]:
695 silc_auth_get_method and silc_auth_get_data.
697 * The server now saves the remote hosts public key to the
698 SilcIDListData pointer. Affected file silcd/protocol.c.
700 * The normal server now does not remove the channel entry from
701 the cache if the founder authentication data is set. It used
702 to remove it if the founder was the last one on the channel on
703 the server and left the channel. The auth data is saved and
704 if the channel is re-joined later the old entry is used with
705 the old auth data. Affected files silcd/command_reply.c and
708 * Removed the `pkcs' field from the SilcIDListData structure
709 in the server; it is not used. Affected file silcd/idlist.h.
711 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Fixed packet processing on slow links. Partial packets were
714 never re-processed because the incoming data buffer was cleared
715 by the application. Application must not directly clear the
716 sock->inbuf, the packet processing routines handle it. Fixed
717 this in client library and in server.
719 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Fixed the WHOIS and IDENTIFY send reply function to really
722 check whether to send list or just one entry. Affected file
725 * Cleaned up the LEAVE command's channel key distribution. The
726 affected file silcd/command.c.
728 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
729 can enforce the channel mode as well. In that case the ID
730 includes the ID of the server. The code now enforces the
731 mode change if the router have different mode than the server.
733 * The notify client operation with CMODE_CHANGE notify can now
734 return NULL client_entry pointer if the CMODE was not changed
735 by client. Application must check for this.
737 * Added <Server ID> argument to INFO command to support server
738 info fetching by Server ID.
740 * Added silc_server_announce_get_channel_users to get assembled
741 packets of channel users of the specified channel. Affected
742 file silcd/server.[ch].
744 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
745 was freed underneath the ID Cache.
747 * Re-announce clients when the server received CHANNEL_CHANGE
748 notify from the router. Affected file silcd/packet_send.c.
750 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
753 crashed since it did not handle the fact that there is no cipher
754 called "3" and didn't check the error condition. Now fixed.
756 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
757 flag. It can be used to send message requests.
759 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Implemented the RESTART command in the client.
763 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
764 notice type messages. Added notice printing to the user
767 * The channel keys are not re-generated if the channel's mode
768 is PRIVKEY, ie private key on the channel exists. Affected
769 files silcd/server.c and silcd/command.c.
771 * Fixed a little bug in channel message delivery when channel
772 private keys are set in the server. Affected file is
775 * Changed the setting on channel->on_channel = TRUE from the
776 silc_client_save_channel_key to the JOIN command reply. The
777 key payload is not received if the private channel key is set.
778 Affected file lib/silcclient/command_reply.c and the
779 lib/silcclient/client_channel.c.
781 * When the CMODE_CHANGE notify is sent and the channel private
782 key mode is removed the channel key must be re-generated in
783 other cells as well. Added this support for the router in the
784 silcd/packet_receive.c.
786 * Added new local command NOTICE to send notice message on
787 channel. Affected file silc/local_command.[ch].
789 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Added new local command ME to the client. It is used to send
792 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
793 some action. Affected file silc/local_command.[ch].
795 * Changed channel_message and private_message client operations
796 to deliver the message flags to the application. Added also
797 the `flags' arguments to the silc_client_send_channel_message
798 and silc_client_send_private_message functions. Affected file
801 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Redefined the Private Message Payload to support private message
804 keys and to support the new private message flags. Updated
805 the protocol specs. Flags makes it possible to have for example
808 * Added new type SilcPrivateMessagePayload and defined an API
809 for it in the lib/silcclient/silcprivate.[ch].
811 * Tested private message private keys successfully. Tested the
812 private message key set, unset and list commands with the new
815 * Redefined the Channel Message Payload to include the channel
816 message flags (equal with private message flags) to support
817 for example CTCP style messages.
819 * Defined some of the message (for channel and private message)
820 flags. Updated the protocol specs and added the flags to the
821 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
823 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Added SilcKeyAgreementStatus type to the key agreement routines
826 to indicate the current status and error if one occured.
827 The status types are defined in the lib/silcclient/silcapi.h.
829 * Added new local command KEY that is used to set and unset private
830 keys for channels, set and unset private keys for private messages
831 with remote clients and to send key agreement requests and
832 negotiate the key agreement protocol with remote client. The
833 key agreement is supported only to negotiate private message keys,
834 it currently cannot be used to negotiate private keys for channels,
835 as it is not convenient for that purpose.
837 * Fixed a minor pending callback setting bug in the function
838 silc_client_get_client_by_id_resolve, now the function works.
839 Affected file lib/silcclient/idlist.c.
841 * Added function silc_net_get_local_port to get local bound
842 port by socket. Added to lib/silcutil/silcnet.[ch].
844 * Added `sockets' and `sockets_count' fields to the SilcClient
845 object. They hold the sockets of the listenning sockets in
846 the client. Listenning sockets may be for example the key
847 agreement server. Affected file lib/silcclient/client.[ch].
848 Added functions the silc_client_add_socket and the
849 silc_client_del_socket. They are exported to the application
852 * Added ~./silc/clientkeys to support other client's public keys.
854 * Renamed verify_server_key client operation to verify_public_key
855 and added one argument to indicate the type of the connection
856 (server, client etc.).
858 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Added silc_server_connection_auth_request to handle the
861 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
862 silcd/packet_receive.[ch].
864 * Added silc_server_send_connection_auth_request into the
865 silcd/packet_send.c to send the connection auth request packet.
867 * Cleaned up the silcd/protocol.c a bit and fixed some memory
870 * Fixed the public key authentication in responder side in the
871 server. The `auth_data' pointer includes the SilcPublicKey
872 not the path to the public key. Affected file silcd/protocol.c.
874 * Implemented the public key authentication in the initiator side
875 in the server. Affected file silcd/protocol.c.
877 * Removed the [RedirectClient] config section from the server
878 configuration. Is not needed and I don't want to implement it.
880 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Cleaned up the CMODE command in the server. It now works
883 correctly and supports all the modes defined in the protocol.
884 Affected file is silcd/command.c.
886 * Added `hmac_name' field to the SilcChannelEntry in the server
887 to hold the default HMAC of the channel. It can be set when
888 creating the channel (with JOIN command). Affected files
891 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
892 type to indicate the change of the current cipher and hmac
893 on the channel. Client can safely ignore the <cipher> argument
894 (if it chooses to do so) since the CHANNEL_KEY packet will
895 force the channel key change anyway. The <hmac> argument is
896 important since the client is responsible of setting the new
897 HMAC and the hmac key into use.
899 * Fixed the CMODE command in the client library as well.
901 * Tested CMODE command in router environment successfully.
903 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Show the version of the remote client (or server) when connecting
906 to the server. It is logged to the log file. Affected file
909 * Fixed the KILLED notify handling in the client library. The
910 client must be removed from all channels when receiving the
913 Also, do not remove the client entry when giving the KILL
914 command but when the KILLED notify is received.
916 * Removed silc_idlist_find_client_by_nickname from the server.
917 Not needed anymore. Affected files silcd/idlist.[ch].
919 * Implemented the CHANNEL_CHANGE notify type handling to the
920 server. Affected file silcd/server.c.
924 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

938 * Added function silc_server_get_client_resolve to find the
939 client entry by ID from all ID lists and then resolve it
940 (using WHOIS) if it cannot be found. Affected file is
943 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Implemented the BAN command to the client library.
947 * The JOIN command in the server now checks the invite list
950 * Changed the silc_command_reply_payload_encode_va and the
951 silc_command_payload_encode_va to support that if argument is
952 NULL it ignores and checks the next argument. Affected file
953 lib/silccore/silccommand.c.
955 * Added silc_server_send_notify_ban to send the BAN notify
956 type between routers.
958 * Chaned the silc_notify_payload_encode to support that if
959 argument is NULL it ignores and checks the next argument.
960 Affected file lib/silccore/silcnotify.c.
962 * Tested ban lists in router environment successfully.
964 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Implemented BAN command to the server, in silcd/command.[ch].
968 * Removed the BAN and INVITE_LIST modes from the CMODE command
971 * Added function silc_string_match to regex match two strings.
972 Affected files lib/silcutil/silcutil.[ch].
974 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Redefined parts of the SilcChannelEntry in the server to support
977 the new ban and invite lists.
979 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Redefined the INVITE command. The same command can be used to
982 invite individuals to the channel but also to manage the invite
983 list of the channel (to add to and remove from the invite list).
984 Updated the protocol specs.
986 * Added new command SILC_COMMAND_BAN that can be used to manage
987 the ban list of the channel. Updated the protocol specs.
989 * Removed the channel modes: the SILC_CMODE_BAN and the
990 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
991 in the CMODE command. The equivalent features are now available
992 using INVITE and BAN commands. Updated the protocol specs.
994 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
995 in the network about change in the current ban list. The notify
996 type is not used by the client.
998 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
999 support the invite lists.
1001 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Added new function silc_string_regexify that converts string
1004 including wildcard characters into regex string that can
1005 be used by the GNU regex library. Added into the file
1006 lib/silcutil/silcutil.[ch].
1008 Added silc_string_regex_combine to combine to regex strings
1009 into one so that they can be used as one regex string by
1010 the GNU regex library. Added into the file
1011 lib/silcutil/silcutil.[ch].
1013 Added silc_string_regex_match to match two strings. It returns
1014 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1016 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Imported GNU regex to the soruce tree into lib/contrib.
1019 Fixed some compiler warning from the regex.c.
1021 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Fixed MOTD command in the server to work in router environment.
1025 * Fixed the MOTD command in the client library to support
1026 the server argument in the command.
1028 * Added `nickname_len' argument to the silc_idlist_add_client
1029 in the server, as the `nickname' argument may be binary data
1032 * Added silc_idlist_get_channels to return all channels from
1035 * Implemented LIST command to the server. Affected file is
1038 * Implemented the LIST command to the client library and on the
1041 * Added [<user count>] argument to the LIST command reply.
1042 With private channels the user count is not shown.
1044 * Updated TODO and README.
1046 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * The client entry's data.registered must be TRUE even with
1049 global client entry on global client list. The data.registered
1050 is used to check whether the client is anymore in the network,
1051 for example with WHOWAS command so it must be valid.
1053 * Fixed the WHOWAS command in the server. It now actually works
1054 in router environment. Added function into silcd/command_reply.c
1055 silc_server_command_reply_whowas_save.
1057 * Added silc_idlist_purge function to the silcd/idlist.c
1058 to periodically purge the ID Cache.

1062 reply. Updated the protocol specs.
1064 * Fixed minor bug in silc_idcache_purge to not purge if the
1065 expire value is zero.
1067 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1068 they were buggy because of the WHOWAS information.
1070 * Fixed local command MSG to handle the async resolving of
1071 the remote client properly. It used to fail the first MSG.
1072 Affected file silc/local_command.c.
1074 * Added `data_len' field to SilcIDCache context.
1076 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Update TODO. Todo in commands in the server.
1080 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1083 used by routers as broadcast packet to inform other routers
1084 about the changed user mode.
1086 Implemented the notify handling in the server. Affected file is
1087 silcd/packet_receive.c. Added the function
1088 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1090 * Added new generic Channel Payload and deprecated the New Channel
1091 Payload. The New Channel Payload is now the generic Channel
1094 * Added new argument `mode' to the silc_server_send_new_channel
1095 as it is required in the Channel Payload now.
1097 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1098 and created a new and real SilChannelPayload to represent the
1099 new generic Channel Payload. Implemented the encode/decode
1100 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1102 * Added silc_server_get_client_channel_list to return the list
1103 of channels the client has joined for WHOIS command reply.
1104 Affected file silcd/server.[ch].
1106 * Implemented the channel list sending in the WHOIS command reply
1107 in server and in the client.
1109 Implemented the channel list displaying on the user interface
1110 as well. Affected file silc/client_ops.c.
1112 * Added silc_channel_payload_parse_list to parse list of Channel
1113 Payloads. It returns SilcDList list of SilcChannelPayloads.
1114 Client for example can use this function to parse the list of
1115 channels it receives in the WHOIS command reply. The caller
1116 must free the list by calling silc_channel_payload_list_free.
1117 Affected files lib/silccore/silcchannel.[ch].
1119 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Added one new argument <user mode> to the WHOIS command reply
1122 to return the mode of the user in SILC. Updated the protocol
1125 Implemented it to the server and client.
1127 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Fixed the mode printing on the user interface on joining.
1130 Affected file silc/client_ops.c.
1132 * Implemented the UMODE command and user modes in general to the
1133 client library and to the user interface.

1137 * The server now sends UNKNOWN_COMMAND error status if client sends
1138 unknown command. Affected file silcd/command.c.
1140 * All server commands now handle the command identifier the right
1141 way when sending the command reply to the client. The client can
1142 use to identify the command replies with the identifier.
1144 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Added silc_server_get_client_route to resolve the route to
1147 the client indicated by the client ID. Affected file is
1150 * Added silc_server_relay_packet as general function to relay
1151 packet to arbitrary destination. This deprecates functions
1152 like _send_private_message_key, _relay_notify etc. Affected
1153 file is silcd/packet_send.[ch].
1155 Removed silc_server_send_key_agreement,
1156 silc_server_send_private_message_key and
1157 silc_server_packet_relay_notify functions from the file
1158 silcd/packet_send.[ch].
1162 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1163 server. Affected file silcd/packet_receive.[ch].
1165 * Implemented the KILL command to the client. Implemented the
1166 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1167 Affected files lib/silcclient/command[_reply].c and
1168 lib/silcclient/client_notify.c. Implemented the KILL notify
1169 printing in the user inteface.
1171 * Fixed a lot silc_parse_nick memory leaks from the client
1172 library in the file lib/silcclient/command.c.
1174 * Changed the silc_server_send_notify_on_channels's `sender'
1175 argument from SilcSocketConnection to SilcClientEntry to
1176 check the sender as entry and not as connection object and not
1177 to send to the client provided as argument. The affected file
1178 is silcd/packet_send.[ch].
1180 * The notify packets that are destined directly to the client used
1181 to not to be processed by the server. Now changed that and the
1182 server processes all notify packets. After relaying the packet
1183 to the client the notify packet is processed in the server.
1185 * The silc_server_free_client_data now checks whether there is
1186 pending outgoing traffic for the client and purges the data to
1187 the network before removing the client entry.
1189 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1192 an client is killed from the SILC Network. Updated the protocol
1195 Added new function silc_server_send_notify_killed to the
1196 silcd/packet_send.[ch].
1198 * Added function silc_server_packet_relay_notify to relay notify
1199 packets that are destined directly to a client. In this case
1200 the server does not process the notify packets but merely relays
1201 it to the client. Affected file silcd/packet_send.[ch].
1203 Added also silc_server_packet_process_relay_notify to check
1204 whereto relay the notify. Affected file is
1205 silcd/packet_receive.[ch].
1207 * Implemented the KILL command to the server.
1211 * Added the backup schema desgined last fall to the protocol
1212 specs for everyone to see. The specification is in the
1213 *-spec-xx.txt draft and the packet type definitions for the
1214 backup routers is in *-pp-xx.txt draft. Thusly, added also
1215 new packet type SILC_PACKET_CELL_ROUTERS.
1217 * A big security problem in the implementation discovered. The
1218 signoff of an client did not cause new channel key generation
1219 which it of course should've done. The channel keys must be
1220 always re-generated when client leaves (or signoffs) the channel.
1221 The silc_server_remove_from_channels funtion now handles
1222 the channel key re-generation.
1224 * Added `sender' argument to the silc_server_send_notify_on_channels
1225 to not to send the client provided as argument. Affected file
1226 silcd/packet_send.[ch].
1228 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Implemented OPER and SILCOPER commands into the server and
1233 * Added silc_auth_verify and silc_auth_verify_data to verify
1234 the authentication directly from the authentication payload.
1235 It supports verifying both passphrase and public key based
1236 authentication. Affected file lib/silccore/silcauth.[ch].
1238 * Added `hash' field to the SilcIDListData structure. It is the
1239 hash negotiated in the SKE protocol. Affected file is
1242 * Slight redesigning of the SilcAuthPayload handling routines.
1243 Do not send SilcPKCS but SilcPublicKey as argument.
1245 * Implemented the public key authentication support to the
1246 serverconfig. The public key is loaded from the provided path
1247 and saved as authentication data to void * pointer. Thus,
1248 changed the unsigned char *auth_data to void *auth_data;
1250 * Fixed SHUTDOWN command to send the reply before the server
1251 is shutdown. :) Affected file silcd/command.c.
1253 * Fixed fatal bug in CONNECT command. The hostname was invalid
1254 memory and server crashed. Affected file silcd/command.c.
1256 * Fixed fatal bug in CLOSE command. The server_entry became
1257 invalid but was referenced later in the command. Affected file
1260 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Fixed fatal bug in failure packet handling. Server ignored
1263 the failure and thus crashed when it came.
1267 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1270 that the command may be executed only once in (about) 2 seconds.
1271 The old SILC_CF_LAG flag is same but allows command bursts up
1272 to five before limiting.
1274 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1275 server code. Various commands now includes the CF_LAG_STRICT
1276 flag to disallow any kind of miss-use of the command.
1278 * Fixed the silc_buffer_unformat to not to allocate any data
1279 if the length of the data is zero. It used to allocate the
1280 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1282 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Changed the format of AdminConnection configuration section
1285 in the server. Added username of the admin to the format.
1286 Affected files silcd/serverconfig.[ch].
1288 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1289 to return admin configuration data by host, username and/or
1292 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Implemented WHOWAS command to the server. Added the functions:
1296 silc_server_command_whowas_parse,
1297 silc_server_command_whowas_send_reply,
1298 silc_server_command_whowas_from_client and
1299 silc_server_command_whowas_from_server
1301 * Added <Client ID> argument to the WHOWAS command reply. Updated
1302 the protocol specs accordingly.
1304 * Implemented WHOWAS command and command_reply to the client
1307 Implemented the WHOWAS printing on the user interface.
1309 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added new argument to the WHOWAS command reply, the real name.
1312 It is an optional argument. Updated the protocol specs.
1314 * Added SilcIDCacheDestructor callback that is registered when
1315 the SilcIDCache is allocated. The callback is called when
1316 an cache entry in the ID Cache expires, or is purged from the
1317 cache. Added into lib/silccore/idcache.[ch].
1319 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1320 to destruct the client entries when the cache entry expires.
1321 Other ID Cache's in server and in the client library ignores
1324 * If the ID Cache entry's `expire' field is zero then the entry
1325 never expires. Added boolean `expire' argument to the
1326 silc_idcache_add function in the lib/silccore/idcache.[ch].
1327 If it is TRUE the default expiry value is used.
1329 * Added silc_server_free_client_data_timeout that is registered
1330 when client disconnects. By default for 5 minutes we preserve
1331 the client entry for history - for WHOWAS command.
1333 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Added support to the server to enforce that commands are not
1336 executed more than once in 2 seconds. If server receives
1337 commands from client more frequently, timeout is registered
1338 to process the commands. Affected file silcd/command.c.
1339 Added new function silc_server_command_process_timeout.
1341 * Changed NICK_NOTIFY handling in client library to check that
1342 if the client's nickname was changed, so there is no need to
1343 resolve anything from the server.
1345 * Removed error printing from the WHOIS and IDENTIFY commands.
1346 If error occurs then it is ignored silently in the client library.
1347 The application, however, may map the received error to
1348 human readable error string. The application currently maps
1349 the NO_SUCH_NICKNAME error to string.
1351 * Made the command status message public to the application. Moved
1352 them from lib/silcclient/command_reply.c to
1353 lib/silcclient/command_reply.h. The application can map the
1354 received command status to the string with the
1355 silc_client_command_status_message function.
1357 * Added check to the server to check that client's ID is same
1358 as the Source ID in the packet the client sent. They must
1361 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Added dist-bzip hook to the Makefile.am to make bzip2
1364 compressed distributions.
1366 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Server now enforces the maximum length for the nickname and
1369 the channel as protocol specification dictates. 128 bytes for
1370 nickname and 256 bytes for channel name.
1372 * Moved the WHOIS printing to the application. The client libary
1373 does not print out the WHOIS information anymore, the application
1374 must do it. Renamed silc_client_command_reply_whois_print to
1375 the silc_client_command_reply_whois_save.
1377 The client's idle time is also sent to the application now, and
1378 the idle is shown on screen.
1380 * Added silc_client_command_reply_identify_save to save the
1381 received IDENTIFY entries.
1383 * Do not check for channel private keys in message sending and
1384 reception if the channel does not have the PRIVKEY mode set.
1385 Affected file lib/silclient/client_channel.c.
1387 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1390 just surfaced after chaning the JOIN procedure.
1392 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1394 * Added silc_client_get_clients_by_list to get client entries
1395 from Client ID list, that is returned for example by JOIN
1396 and USERS command replies. The application should use this
1397 function for example when JOIN command reply is received to
1398 resolve the clients already on the channel (library does not
1399 do that anymore as USERS command reply is not used in the JOIN
1400 procedure anymore). Affected files lib/silcclient/silcapi.h and
1401 lib/silcclient/idlist.c.
1403 * JOIN command reply and USERS command reply returns now SilcBuffer
1404 pointers instead of unsigned char pointers when returning
1405 the client list and mode list.
1407 * Added <Client ID> argument to the JOIN command reply, mainly
1408 for the server to identify for which client the command was
1409 originally sent. Updated protocol specs accordingly.
1411 * Added SilcDlist private_key pointer to the SilcChannelEntry
1412 in the client to support the channel private keys. Affected
1413 file is lib/silcclient/idlist.h.
1415 * Added SilcChannelPrivateKey argument to the function
1416 silc_client_send_channel_message so that application can choose
1417 to use specific private ke if it wants to. If it is not provided,
1418 the normal channel key is used, unless private keys are set.
1419 In this case the first (key that was added first) is used
1420 as the encryption key.
1422 * Implemented the support for channel private key handling.
1423 Implemented the following functions:
1425 silc_client_add_channel_private_key,
1426 silc_client_del_channel_private_keys,
1427 silc_client_del_channel_private_key,
1428 silc_client_list_channel_private_keys and
1429 silc_client_free_channel_private_keys
1431 Affected file lib/silcclient/client_channel.c.
1433 * Added the support for the private keys in the channel message
1434 sending and encryption and in the message reception and
1435 decryption. Affected funtions are
1436 silc_client_send_channel_message and silc_client_channel_message.
1438 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Added SKE's key verify callback to the client library's
1441 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1443 * Removed the statement that server (or router) must send USERS
1444 command reply when joining to the channel so that the client
1445 knows who are on the channel. Instead, the client list and
1446 client's mode list is now sent in the JOIN command reply to the
1447 client who joined channel. This is better solution.
1449 * Added function silc_server_get_users_on_channel and function
1450 silc_server_save_users_on_channel to the silcd/server.[ch].
1452 * Removed function silc_server_command_send_users from the
1455 * Do not show topic on the client library anymore. The topic is
1456 sent in the command reply notify to the application and the
1457 application must show the topic now.
1459 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Added client searching by nickname hash into the IDENTIFY and
1462 WHOIS commands in the server as they were clearly missing from
1463 them. Affected file is silcd/command.c.
1465 * Fixed a bug in private message receiving in the client library.
1466 The remote ID was freed and it wasn't supposed, now it is
1469 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Minor fix to the channel payload; allocate the data area, as it
1472 needs to be of specific length.
1474 * If the key agreement port is zero then the operating
1475 system will define the bound port. Affected files are
1476 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1478 * Added new function silc_channel_payload_decrypt into the file
1479 lib/silccore/silcchannel.[ch].
1481 * Moved the channel message etc, check from silc_packet_decrypt
1482 to applications. The library calls now a generic
1483 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1484 when the packet is either normal or special. This was done to
1485 allow more wide range of checking that was not allowed when
1486 the code was in library. Now applications can do virtually any
1487 checks to the packet and return to the library the decision how
1488 the packet should be processed. Affected files are
1489 lib/silccore/silcpacket.[ch].
1491 Added silc_server_packet_decrypt_check to the server and
1492 silc_client_packet_decrypt_check to the client library.
1494 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1495 to send with specified source and destination information.
1497 * Channel message delivery between routers was broken after the
1498 channel key distribution was fixed earlier. The channel key
1499 was used be to distributed to other routers as well which is not
1500 allowed by the protocol. Now this is fixed and channel keys
1501 really are cell specific and the channel message delivery between
1502 routers comply with the protocol specification.
1504 * Fixed various commands in server to check also the global list
1505 for the channel entry and not just the local list. The affected
1506 file silcd/command.c.
1508 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Added assert()s to buffer formatting and unformatting routines
1511 to assert (if --enable-debug) when error occurs. Affected
1512 file: lib/silcutil/silcbuffmt.c.
1514 * Changed to auto-reconnect to check whether the remote host is
1515 router and register the re-connect timeout if it is. It used
1516 to check that whether we are normal server, but router must do
1517 auto-reconnect with another router as well. Affected file
1520 * Removed the [<key len>] option from CMODE command as the cipher
1521 name decides the key length, nowadays. See the defined ciphers
1522 from the protocol specification.
1524 * Added [<hmac>] option to the CMODE command to define the HMAC
1525 for the channel. Added SILC_CMODE_HMAC channel mode.
1527 * Added [<hmac>] option for the JOIN command so that user can
1528 select which HMAC is used to compute the MACs of the channel
1531 * Added Hmac field to the Channel Message Payload. The integrity
1532 of plaintext channel messages are now protected by computing
1533 MAC of the message and attaching the MAC to the payload. The
1534 MAC is encrypted. Now, it is clear that this causes some
1535 overhead to the size of the packet but rationale for this is that
1536 now the receiver can verify whether the channel message decrypted
1537 correctly and also when private keys are set for the channel the
1538 receiver can decrypt the packet with several keys and check from
1539 the MAC which key decrypted the message correctly.
1541 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1542 lib/silccrypt/silccipher.[ch].
1544 * Added silc_hash_len to return the digest length into the
1545 lib/silcrypt/silchash.[ch].
1547 * Rewrote parts of Silc Channel Payload interface in the
1548 lib/silccore/silcchannel.[ch]. The encode function now also
1549 encrypts the packet and parse function decrypts it.
1551 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Fixed a minor formatting bug in the SKE's key material processing.
1554 It actually might have processed the keys wrong way resulting
1557 * Redefined the mandatory HMAC algorithms and added new algorithms.
1558 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1559 and hmac-md5 truncated to 96 bits. The mandatory is now
1560 hmac-sha1-96. Rest are optional (including the one that used
1561 to be mandatory). Rationale for this is that the truncated HMAC
1562 length is sufficient from security point of view and can actually
1563 make the attack against the HMAC harder. Also, the truncated
1564 HMAC causes less overhead to the packets. See the RFC2104 for
1567 * Added new [hmac] configuration section. The SKE used to use
1568 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1569 is of course wrong. The official names that must be proposed in
1570 the SKE are the ones defined in the protocol specification
1571 (hmac-sha1-96 for example). The user can configure any hmac
1572 using any hash function configured in the [hash] section. At
1573 least, the mandatory must be configured.
1575 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1577 * Added HMAC list to the SKE proposal list. It has now both
1578 hash algorithm list and HMAC list. This makes the protocol
1579 incompatible with previous versions. The SKE now seems to work
1580 the way it is supposed to work, for the first time actually.
1582 * Defined plain Hash algorithms to the protocol specification.
1585 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Implemented support for key agreement packets into the server.
1588 Added functions silc_server_key_agreement and
1589 silc_server_send_key_agreement. Other than these functions,
1590 server has nothing to do with this packet.
1592 * Added support for private message key packets into the server.
1593 Added functions silc_server_private_message_key and
1594 silc_server_send_private_message_key.
1598 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1599 called in the protocol's final callback instead in the END
1600 protocol state. This makes a little more sense and in the same
1601 time in client we can use the same protocol routines for normal
1602 key exchange and to key agreement packet handling as well.
1604 * Added to both client's and server's KE protocol context the
1605 SilcSKEKeyMaterial pointer to save the key material. We will
1606 bring the key material to the protocol's final callback by doing
1607 this. The final callback must free the key material.
1609 * Added SKE's packet_send callback into client's KE protocol
1610 context so that the caller can choose what packet sending function
1611 is used. This way we can use different packet sending when
1612 doing normal SKE when doing key agreement packet handling (in
1613 the key agreement packet handling we do not want to encrypt
1616 * Implemented the responder side of the key agreement routines
1617 in the client. The client can now bind to specified port and
1618 accept incoming key negotiation. The key material is passed
1619 to the application after the protocol is over.
1621 * Implemented the processing of incoming Key Agreement packet
1622 in the client. Added function silc_client_key_agreement to
1625 * Implemented the intiator side of the key agreement routines
1626 in the client. The client can now initiate key agreement with
1627 another remote client. The key material is passed to the
1628 application after the protocol is over.
1630 * Created client_keyagr.c to include all the key agreement
1633 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1634 SILC_TASK_CALLBACK except that it is not static.
1636 * Created client_notify.c and moved the Notify packet handling
1637 from the client.[ch] into that file.
1639 * Created client_prvmsg.c and moved all private message and
1640 private message key routines from the client.[ch] into that file.
1642 * Create client_channel.c and moved all channel message and
1643 channel private key routines from the client.[ch] into that file.
1645 * Changed silc_client_get_client_by_id_resolve to resolve with
1646 WHOIS command instead of IDENTIFY command, in the file
1647 lib/silclient/idlist.c.
1649 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Implemented the SKE's responder side to the Client library.
1653 * When FAILURE is received to the protocol do not trust it
1654 blindly. Register a timeout to wait whether the remote closes
1655 the connection as it should do it, only after that process the
1656 actual failure. This was changed to both client and server.
1658 * Added client_internal.h to include some of the structures
1659 there instead of client.h in lib/silcclient/.
1661 * Added function silc_task_unregister_by_callback to unregister
1662 timeouts by the callback function.
1664 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Some "Incomplete WHOIS info" errors has been appearing on the
1667 log files. Took away the entry->userinfo check from WHOIS
1668 reply sending. The entry->userinfo is now " " if client did not
1669 provide one. I thought this was fixed earlier but something
1670 is wrong still. Let's see if the error still appears.
1672 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Fixed a minor bug in the login when the channel key is
1675 re-generated in the server. It used to generate the key in
1676 wrong order and thus caused problems in the channel traffic.
1678 * Fixed a minor bug in channel key distsribution after
1679 KICK command. The key was not sent to the router even though
1682 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Added silc_ske_process_key_material_data as generic routine
1685 to process any key material as the SILC protocol dictates. The
1686 function is used by the actual SKE library but can be used by
1687 applications as well. This relates to the private message keys
1688 and the channel private keys since they must be processed the
1689 same way the normal SILC session keys. The protocol dictates
1690 this. Affected files: lib/silcske/silcske.[ch].
1692 Added also silc_ske_free_key_material to free the
1693 SilcSKEKeyMaterial structure.
1695 * Defined silc_cipher_set_key function to set the key for
1696 cipher without using the object's method function. The affected
1697 files: lib/silccrypt/silccipher.[ch].
1699 * Implemented silc silc_client_add_private_message_key,
1700 silc_client_add_private_message_key_ske,
1701 silc_client_del_private_message_key,
1702 silc_client_list_private_message_keys and
1703 silc_client_free_private_message_keys functions in the
1706 Added functions silc_client_send_private_message_key to send
1707 the Private Message Key payload and silc_client_private_message_key
1708 to handle incoming Private Message Key payload.
1710 * Added Cipher field to the Private Message Key payload to set
1711 the cipher to be used. If ignored, the default cipher defined
1712 in the SILC protocol (aes-256-cbc) is used.
1714 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Removed lib/silcclient/ops.h file.
1718 Redefined parts of the SILC Client Library API. Created new
1719 file silcapi.h that deprecates the ops.h file and defines the
1720 published Client Library API. Defined also private message key
1721 API and channel private key API into the file.
1723 This is the file that the application must include from the
1724 SILC Client Library. Other files need not be included by
1725 the application anymore.
1727 * Added new key_agreement client operation callback and also
1728 defined the Key Agreement library API for the application.
1730 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1733 is used by clients to request key negotiation between another
1734 client in the SILC network. If the negotiation is started it
1735 is performed using the SKE protocol. The result of the
1736 negotiation, the secret key material, can be used for example
1737 as private message key.
1739 Implemented the Key Agreement payload into the files
1740 lib/silccore/silauth.[ch].
1742 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1744 * Redefined ciphers for the SILC protocol. Added some new ciphers
1745 and defined the key lengths for the algorithms. Changed the
1746 code accordingly. The default key length is now 256 bits.
1748 * Fixed SKE key distribution function silc_ske_process_key_material
1749 when the key length is more than 128 bits. The default key
1750 length in SILC is now 256 bits.
1752 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1753 to indicate unsupported algorithm.
1755 * Renamed rijndael.c to aes.c and all functions as well.
1757 * Fixed a long standing channel key setting bug in client library.
1758 Weird that it has never surfaced before.
1760 * Fixed bug in channel deletion. If the entire channel is removed
1761 then it must also delete the references of the channel entry
1762 from the client's channel list as the client's channel entry and
1763 the channel's client entry share same memory.
1765 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Implemented CONNECT and SHUTDOWN commands in the client.
1769 * Implemented CLOSE command to the client.
1771 * Added the function silc_idlist_find_server_by_name into the
1772 files silcd/idlist.[ch].
1774 Added the function silc_idlist_find_server_by_conn into the
1775 files silcd/idlist.[ch].
1777 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * DIE command was renamed to SHUTDOWN. Updated the both code
1782 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1783 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1785 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1788 * Added function silc_server_create_connection function to create
1789 connection to remote router. My server implementation actually
1790 does not allow router to connect to normal server (it expects
1791 that normal server always initiates the connection to the router)
1792 so the CONNECT command is only good for connecting to another
1795 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1798 or some other client was kicked from the channel.
1800 Implemented the handling of the notify type to both client
1803 Implemented silc_server_send_notify_kicked to send the KICKED
1804 notify. It is used to send it to the server's primary router.
1806 * Implemented the KICK command into server and client.
1808 * Added `query' argument to the silc_idlist_get_client function
1809 to indicate whether to query the client from server or not if
1812 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1813 to indicate that the client is not channel founder.
1817 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Removed the rng context from SilcPacketContext structure and
1820 changed that the packet routine uses the Global RNG API.
1822 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added support for quit message that client can "leave" on the
1825 channel when it quits the SILC. It is ditributed inside the
1826 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1828 Added silc_server_free_client_data that will take the
1829 signoff message as argument.
1831 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1833 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Updated parts of the protocol specification to keep it up
1838 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1841 payloads in one packet.
1843 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1844 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1845 use now the new List flag.
1847 * Also deprecated the following packet types: REPLACE_ID,
1848 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1850 * Added list support for Notify packet in server.
1852 * Added silc_server_send_notify_channel_change to send the
1853 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1854 the silc_server_send_replace_id.
1856 * Added silc_server_send_notify_nick_change to send the
1857 NICK_CHANGE notify type. Deprecates the function
1858 silc_server_send_replace_id.
1860 * Added silc_server_send_notify_join to send the JOIN notify type.
1861 Deprecates the function silc_server_send_new_channel_user.
1863 * Added silc_server_send_notify_leave to send LEAVE notify type.
1864 Deprecates the function silc_server_send_remove_channel_user.
1866 * Added silc_server_send_notify_cmode and
1867 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1868 types. Deprecates the silc_server_send_set_mode function.
1870 * Added SERVER_SIGNOFF notify type to indicate that server has
1871 quit. This means that all clients on the channel from that
1872 server will drop. This can be also used when netsplit happens.
1874 Deprecated REMOVE_ID packet type since it is not needed anymore
1877 Added silc_server_send_notify_server_signoff to send the
1878 SERVER_SIGNOFF notify type. Deprecates the function
1879 silc_server_send_remove_id.
1881 Added also silc_server_send_notify_signoff to send the
1882 SIGNOFF notify type.
1884 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1885 SILC protocol from this day on. Changed the protocol
1886 specification as well.
1888 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1889 notify type. It is used between routers to notify about
1890 topic changes on a channel.
1892 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1895 * Partly updated the protocol specification to comply with the
1896 changes now made. It is still though a bit outdated.
1898 * The JOIN notify type now takes one extra argument <Channel ID>.
1899 The packet used to be destined to the channel but now the
1900 JOIN type may be sent as list thus it is impossible to
1901 destine it to any specific channel. By adding this argument
1902 it is again possible.
1904 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Added CREDITS file. The CHANGES and CREDITS file will appear
1907 in the distribution as well.
1909 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1912 types in the server's silcd/packet_receive.c.
1914 * Implemented CMODE and CUMODE to work in router environment.
1916 * Fixed minor encoding and decoding buglet from the
1917 lib/silccore/silcmode.c.
1919 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1922 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1924 * Changed all SilcConfigServer* and silc_config_server* to
1925 SilcServerConfig* and silc_server_config*, respectively.
1928 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Associated the ID (client or server ID) to the Authentication
1931 Payload to avoid any possibility of forging. Updated the
1932 protocol specification and the code accordingly.
1934 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * The RSA key length is now save to the RsaKey context in the
1937 key generation process in lib/silccrypt/rsa.c. The key length
1938 is now used to figure out the maximum size of the block allowed
1939 to be encrypted/signed.
1941 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1942 is equivalent to the silc_mp_mp2bin but does not allocate any
1945 * Changed silc_mp_mp2bin API to take length argument. If it is
1946 non-zero then the buffer is allocated that large. If zero, then
1947 the size is approximated using silc_mp_sizeinbase, which however
1950 * Created Global RNG API which is global RNG that application can
1951 initialize. After initializing, any routine anywhere in the
1952 code (including library) can use RNG without allocating a new
1953 RNG object. This was done to allow this sort of use of the
1954 RNG in code that has no chance to allocate RNG object. All
1955 applications currently allocate this and many routines in the
1956 library use this. Affected file lib/silccrypt/silcrng.[ch].
1958 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1959 it to use the Global RNG API.
1961 * Defined Authentication Payload into protocol specification that
1962 is used during SILC session to authenticate entities. It is
1963 used for example by client to authenticate itself to the server
1964 to obtain server operator privileges.
1966 Implemented this payload into the lib/silccore/silcauth.[ch].
1967 Implemented also routines for public key based authentication
1968 as the new protocol specification dictates.
1970 Moved definitions of different authentication methods from
1971 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1973 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1974 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1975 silc_pkcs_verify_with_hash functions into the file
1976 lib/silccrypt/silcpkcs.[ch].
1978 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * The client entry's userinfo pointer must be always valid.
1981 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1982 will fail since it requires the userinfo. Now, the userinfo
1983 is allocated as "" if actual userinfo does not exist. Actually,
1984 it must exist and it is totally Ok to drop client connections
1985 that does not announce the userinfo. However, we will make
1986 this workaround for now.
1988 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1989 to return the remote port by socket.
1991 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1994 SILC_SERVER_PENDING_EXEC and added an new macro
1995 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1996 data or when error occurs while processing the pending command.
1998 Added new argument `destructor' into silc_server_command_pending
1999 and to the SilcServerCommandPending object. This destructor is
2000 now called after calling the pending callback or if error occurs
2001 immediately. If error occurs the actual pending callback won't
2002 be called at all - only the destructor. The destructor may be
2003 NULL if destructor is not needed.
2005 All this applies for client library code as well. Similar
2006 changes were made there as well for the pending commands.
2008 In the client, the application must now allocate the
2009 SilcClientCommandContext with the silc_client_command_alloc
2012 * Added reference counter to the SilcServerCommandContext. Added
2013 function silc_server_command_alloc and silc_server_command_dup
2016 Same type of functions added to the client library for the same
2019 * Removed the cmd_ident from IDListData away since it is now
2020 global for all connections. It is the command identifier used
2021 in command sending and with pending commands. The affected file
2024 * Added reference counter to the SilcSocketConnection objecet to
2025 indicate the usage count of the object. The object won't be
2026 freed untill the reference counter hits zero. Currently only
2027 server uses this, and client ignores it. The client must be
2028 set to use this too later. The affected files are
2029 lib/silccore/silcsockconn.[ch]. Added also the function
2030 silc_socket_dup to increase the reference counter.
2032 This was mainly added because it is possible that the socket
2033 is removed underneath of pending command or other async
2034 operation. Now it won't be free'd and proper DISCONNECTING
2035 flags, etc. can be set to avoid sending data to connection that
2036 is not valid anymore.
2038 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2039 the connection. After that it sets SILC_SET_DISCONNECTED.
2040 It is, however, possible that the socket data is not still freed.
2041 The silc_server_packet_process now checks that data is not
2042 read or written to connection that is DISCONNECTED. The socket
2043 get's freed when the reference counter hits zero.
2045 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Changed the client operation API: channel_message operation's
2048 `sender' is now the client entry of the sender, not the nickname
2049 and the `channel' is the channel entry, not the channel name.
2051 In the private_message operation the `sender' is now also the
2052 client entry of the sender not the nickname.
2054 Affected file is lib/silcclient/ops.h and all applications
2055 using the client operations.
2057 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Moved the calling of ops->connect() from connect_to_server_final
2060 into receive_new_id functin since that is the point when the
2061 client is actually allowed to send traffic to network. The
2062 affected file is lib/silcclient/client.c.
2064 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2067 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2068 (if needs broadcasting) instead of broadcasting the packets one
2069 by one which would make a burst in the network traffic.
2071 * Added `broadcast' argument to the functions in silcd/server.[ch]
2072 silc_server_create_new_channel[_with_id] to indicate whether
2073 to send New Channel packet to primary router.
2075 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Added new function into the silcd/server.[ch] files:
2078 silc_server_create_new_channel_with_id to create new channel with
2079 already existing Channel ID.
2081 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2082 lib/silccore/silcpacket.h. This packet is used t send list of
2083 Set Mode payloads inside one packet. Server uses this to set
2084 the modes for the channels and clients on those channels, that it
2085 announced to the router when it connected to it. The protocol
2086 specification has been updated accordingly.
2088 * The silc_server_new_channel did not handle the packet coming
2089 from normal server as it normally does not send that. However,
2090 when it announces its channels it does send it. Implemented
2091 the support for that.
2093 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2094 into the file lib/silccore/id.h.
2096 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Fixed memory leaks in the functions silc_idlist_del_client,
2099 silc_idlist_del_channel and silc_idlist_del_server in the file
2100 silcd/idlist.c. All of those leaked like a sieve.
2102 * Fixed some small memory leaks in the client's function
2103 silc_client_notify_by_server.
2105 * Added functions into silcd/server.c: silc_server_announce_clients,
2106 silc_server_announce_channels and silc_server_announce_server.
2107 These functions are used by normal and router server to announce
2108 to its primary router about clients, channels and servers (when
2109 router) that we own. This is done after we've connected to the
2112 These functions effectively implements the following packet types:
2113 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2114 and SILC_PACKET_NEW_ID_LIST.
2116 * Added new functions into the silcd/packet_receive.[ch]:
2117 silc_server_new_id_list, silc_server_new_channel_list and
2118 silc_server_new_channel_user_list to handle the incoming
2119 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2121 * Added support of changing Channel ID in the function
2122 silc_server_replace_id. If the server that announces a channel
2123 to the router already exists in the router (with same name but
2124 with different Channel ID), router is responsible to send
2125 Replace ID packet to the server and force the server to change
2126 the Channel ID to the one router has.
2128 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2129 client that the Channel ID has been changed by the router. The
2130 normal server sends this to the client. Client must start using
2131 the new Channel ID as the channel's ID.
2133 Implemented handling of this new type into lib/silcclient/client.c
2134 into the function silc_client_notify_by_server.
2136 * Added new function silc_idlist_replace_channel_id into the files
2137 silcd/idlist.[ch] to replace the Channel ID.
2139 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Call silc_server_command_identify_check always when processing
2142 the IDENTIFY command in silcd/command.c
2144 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2147 send keepalive packets. The packet can be sent by clients,
2148 servers and routers.
2150 Added function silc_socket_set_heartbeat into the file
2151 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2152 If not set, the heartbeat is not performed. The actual
2153 heartbeat is implemented in the low level socket connection
2154 library. However, application is responsible of actually
2157 Added silc_server_send_heartbeat to send the actual heartbeat
2158 packet into silcd/packet_send.[ch]. Server now performs
2159 keepalive with all connections.
2161 * Added silc_task_get_first function into lib/silcutil/silctask.c
2162 to return the timeout task with shortest timeout. There was a bug
2163 in task unregistration that caused problems. TODO has been
2164 updated to include that task system must be rewritten.
2166 * The client library will now resolve the client information when
2167 receiving JOIN notify from server for client that we know but
2168 have incomplete information.
2170 * Rewrote parts of silc_server_remove_from_channels and
2171 silc_server_remove_from_one_channel as they did not remove the
2172 channel in some circumstances even though they should've.
2174 * Encryption problem encountered in server:
2176 The LEAVE command used to send the Channel Key packet to the
2177 router immediately after generating it. However, the code
2178 had earlier sent Remove Channel user packet but not immediately,
2179 ie. it was put to queue. The order of packets in the router
2180 was that Channel Key packet was first and Remove Channel User
2181 packet was second, even though they were encrypted in the
2182 reverse order. For this reason, MAC check failed. Now, this
2183 is fixed by not sending the Channel Key packet immediately but
2184 putting it to queue. However, this is more fundamental problem:
2185 packets that are in queue should actually not be encrypted
2186 because packets that are sent immediately gets encrypted
2187 actually with wrong IV (and thus MAC check fails). So, packets
2188 that are in queue should be encrypted when they are sent to
2189 the wire and not when they put to the queue.
2191 However, the problem is that the current system has not been
2192 designed to work that way. Instead, the packet is encrypted
2193 as soon as possible and left to the queue. The queue is then
2194 just purged into wire. There won't be any fixes for this
2195 any time soon. So, the current semantic for packet sending
2198 o If you send packet to remote host and do not force the send
2199 (the packet will be in queue) then all subsequent packets to the
2200 same remote host must also be put to the queue. Only after the
2201 queue has been purged is it safe again to force the packet
2204 o If you send all packets immediately then it safe to send
2205 any of subsequent packets through the queue, however, after
2206 the first packet is put to queue then any subsequent packets
2207 must also be put to the queue.
2209 Follow these rules and everything works fine.
2211 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Added new function silc_server_remove_clients_by_server to
2214 remove all client entries from ID list when the server connection
2215 is lost. In this case it is also important to invalidate all
2216 client entires as they hold the invalid server entry. This
2217 fixes fatal bug when server has lost connection and will reconnect
2220 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Made some sanity checks to silc_server_daemonise like to check
2223 whether the requested user and group actually exists.
2225 * Added sanity check to SKE's silc_ske_responder_finish to check
2226 that the public and private key actually is valid.
2228 * Invalidate the client's nickname when receiving Replace ID
2229 packet and the Client ID is being replaced. This means that the
2230 server will query the nickname if someone needs it (client)
2233 * Sort the ID Cache in client library when the ID Cache data
2234 has changed (needs sorting).
2236 * Do not allow for SILC client to create several connections to
2237 several servers. The client does not support windows right now
2238 and generating multiple connections causes weird behaviour.
2240 Irssi-silc client does support windows and can handle several
2241 connections without problems, see: www.irssi.org and SILC plugin.
2243 * Fixed some places where client was added to the IDList. The
2244 rule of thumb is following (in order to get everything right):
2245 If the client is directly connected local client then the
2246 `connection' argument must be set and `router' argument must be
2247 NULL to silc_idlist_add_client function. If the client is not
2248 directly connected client then the `router' argument must
2249 bet set and the `connection' argument must be NULL to the
2250 silc_idlist_add_client function.
2252 * The funtion silc_server_packet_send_local_channel actually did
2253 not check whether the client was locally connected or not. It
2254 does that now. Fixed a bug related to LEAVE command.
2256 * Fixed Remove Channel User payload parsing bug in server's
2257 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2259 * The server's silc_server_save_channel_key now checks also the
2260 global ID list for the channel as it might not be in the local
2261 list. Fixed a bug related to LEAVE command.
2263 * Is this the end of the [<unknown>] buglet that has been lurking
2264 around for a long time? A little for loop fix in server's
2265 silc_server_command_whois_parse that is used by both IDENTIFY
2266 and WHOIS command. At least, this was a clear bug and a cause
2267 of one type of [<unknown>] buglet.
2269 * WHOIS and IDENTIFY commands call the function
2270 silc_server_command_[whois/identify]_check function even if
2271 we are not router server.
2273 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Added --with-gmp configuration option. If set the GMP
2276 is always compiled in the SILC source tree. If not set then
2277 it is checked whether the system has the GMP3 installed. If
2278 it has then the GMP won't be compiled (the system's headers
2279 and library is used), if it doesn't have it then the GMP is
2280 compiled in the SILC source tree.
2282 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Changed RSA private exponent generation to what PKCS #1
2285 suggests. We try to find the smallest possible d by doing
2286 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2287 not security fix but optimization.
2289 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Added new config entry [Identity] to fork the server and run
2292 it as specific user and group. A patch from Bostik.
2294 * Imported Dotconf configuration library into lib/dotconf.
2295 This will be used to create the SILC configuration files later.
2296 It will appear in the distsribution after this commit.
2298 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * A big code auditing weekend happening. Auditing code for
2301 obvious mistakes, bugs and errors. Also, removing any code
2304 Removed files for being obsolete:
2306 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2307 inline in the file lib/silcutil/silcbuffer.h)
2309 o lib/silcutil/silcbufutil.c (the header has inline versions)
2311 Changed code to fix possible error conditions:
2313 o The buffer formatting routines now check that the destination
2314 buffer really has enough space to add the data. This applies for
2315 both buffer formatting and unformatting
2316 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2317 unformatting was changed to accomodate following rules:
2318 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2319 sent to the function while XXX_*STRING will not allocate or copy
2320 the data into the buffer. Instead it sets the pointer from the
2321 buffer into the pointer sent as argument (XXX_*STRING used to
2322 require that the pointer must be allocated already). This change
2323 makes this whole thing a bit more consistent and more optimized
2324 (note that the data returned in the unformatting with XXX_*STRING
2325 must not be freed now). The routines return now -1 on error.
2327 o Tried to find all code that use buffer_format and buffer_unformat
2328 and added return value checking to prevent formatting and
2329 especially unformatting errors and possible subsequent fatal
2332 o Changed ske->x and ske->KEY to mallocated pointers in
2333 lib/silcske/silcske.h. Fixed possible data and memory leak.
2335 o Added return value checking to all *_parse* functions. Fixed
2336 many memory leaks as well.
2338 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2339 so that buffer overflows would not happen. All code now also
2340 checks the return value as it can fail.
2342 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added reconnection support to server if the normal server looses
2345 its connection to the router (for example if router is rebooted).
2346 The server performs normal reconnection strategy implemented
2347 to the server. Affected file silcd/server.c.
2349 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Added new packet type SILC_PACKET_SET_MODE that is used to
2352 distribute the information about changed modes (for clients,
2353 channels and clients channel modes) to all routers in the
2354 network. Updated the protocol specification accordingly.
2356 Added functions into silcd/packet_send.c and
2357 silcd/packet_receive.c: silc_server_send_set_mode,
2358 silc_server_set_mode.
2360 Added new files silcmode.[ch] into lib/silccore that implements
2361 the encoding and decoding of Set Mode Payload. Added new type
2362 SilcSetModePayload. Moved the definitions of different modes
2363 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2365 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Oops, a little mistake in server's connection authentication
2368 protocol. The protocol is not ended with FAILURE but with
2369 SUCCESS if the authentication is Ok. :) Affected file is
2372 * Implemented NICK_CHANGE notify handling in server in the file
2373 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2374 the local clients on the channel. After the changing nickname
2375 in router environment snhould work and the [<unknown>] nickname
2376 should appear no more.
2378 The silc_server_replace_id function that receives the Replace ID
2379 payload now sends the NICK_CHANGE notify type also in the file
2380 silcd/packet_receive.c
2382 * Changed WHOIS and IDENTIFY command to support the maximum amount
2383 of arguments defined in protocol specs (3328 arguments). This
2384 fixed a bug that caused problems when there were more than three
2387 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Added extra parameter, command identifier, to the
2390 silc_client_send_command so that explicit command identifier
2393 Changed that ID list routines uses specific command identifier
2394 when sending WHOIS/IDENTIFY requests to the server so that they
2395 can be identified when the reply comes back.
2397 Affected files lib/silcclient/command.[ch],
2398 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2400 * Added `sender' argument to silc_server_packet_send_to_channel
2401 to indicaet the sender who originally sent the packet to us
2402 that we are now re-sending. Ignored if NULL. Affected file
2403 silcd/packet_send.[ch].
2405 * Added some server statistics support in silcd/server_internal.h
2406 SilcServerStatistics structure and around the server code. Also
2407 send some nice statistics information when client is connecting
2410 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Fixed channel ID decoding in server's JOIN command reply in
2413 silcd/command_reply.c
2415 * Fixed braodcasting of replace ID payload to not to send it if
2416 we are standalone server in silcd/packet_receive.c.
2418 * Fixed all channel message sending routines to not to send
2419 packets to clients that has router set, since they are routed
2420 separately in the same function earlier. Affects file
2421 silcd/packet_send.c and all channel packet sending functions.
2423 * In USERS reply, res_argv[i] are not allocated, the table
2424 is allocated. Thus changed that free the table, not its
2427 * In server's whois_check and identify_check if the client is
2428 locally connected do not send any WHOIS commands - they are not
2431 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Fixed some minor bugs in client when sending WHOIS command. The
2434 arguments was in wrong order.
2436 * Removed statis function add_to_channel from server in
2437 silcd/command.c that was previously used with the joining but
2440 * Tested USERS command in router environment successfully with two
2441 routers, two servers and two clients.
2443 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Reorganized the USERS command and command reply in client library
2446 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2447 When the command is given by user we register a pending command
2448 callback that will reprocess the command after the reply has been
2449 received from the server. When reprocessing the packet we then
2450 display the information. Thus, the USERS information is displayed
2451 now in the command callback instead of in the command reply
2452 callback. The processing of the command is same as previously
2453 when server has sent the command reply in the JOINing process.
2455 * Added to USERS command in silcd/command_reply.c to join the client,
2456 we didn't use to know about, to the channel after we've created
2457 a client entry for it. Also, for clienet we did know already still
2458 check whether it is on the channel or not and add it if not.
2460 * Removed silc_server_command_join_notify as the function and its
2463 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Changed the client's pending command handling to the same as the
2466 server's pending command handling. It is also now possible to
2467 execute command reply functions from other command reply
2468 function as the function callbacks for commands and command
2469 replies are one and same. The pending commands are not static
2470 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2471 in client connection context. Thus, pending commands are server
2472 connection specific as it is convenient.
2474 Changed the function silc_client_command_pending and
2475 silc_client_command_pending_del and added new function
2476 silc_client_command_pending_check. Removed the
2477 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2480 * Added cmd_ident, current command identifier, to the client
2481 connection context in lib/silcclient/client.h to keep track on
2482 command identifiers used in command sending. Client's command reply
2483 function handling now supports the mandatory command identifiers.
2485 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2486 funtions in client to fully support pending command callbacks.
2488 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2489 as one of the arguments to the application in the command reply
2492 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2493 before first releasing SILC but came back. Now it is removed again
2494 and should come back nomore. The FORWARDED flag was used only
2495 by the JOINing procedure by forwarding the command packet to router.
2496 Now, the JOINing procedure has been changed to more generic (due
2497 to various router environment issues) and FORWARDED is not needed
2498 anymore for anything. The protocol specification is yet to be
2501 Now, removed silc_server_packet_forward from server and the flag
2502 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2504 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Renamed NAMES command to USERS command. The NAMES was named that
2507 due to historical reasons. Now it is renamed. Also, rewrote
2508 parts of the USERS command. The nickname list is not sent anymore
2509 by the server. Only Client ID and mode lists are sent in the USERS
2510 command. Changed this also to the protocol specification.
2512 The client now resolves the names and stuff after it receives
2513 the USERS list from the server when joining to the channel.
2515 * WHOIS and IDENTIFY commands has been changed to support multiple
2516 Client ID's per command. One can now search for multiple users
2517 in the network by sending only one WHOIS or IDENTIFY command.
2518 Changed the code and the protocol specifications.
2520 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2521 uses silc_server_command_whois_parse to parse the request. */
2523 * If normal server, do not parse the WHOIS and IDENTIFY requests
2524 before sending it to the router. Saves some time.
2526 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Fixed JOIN command on client library. Wrong number of arguments
2529 used to crash the client.
2531 * Added silc_server_channel_has_global function to check whether
2532 channel has global users or not.
2534 * Added silc_server_channel_has_local function to check whether channel
2535 has locally connected clients on the channel.
2537 * The silc_server_remove_from_one_channel now checks whether the
2538 channel has global users or not after given client was removed from
2539 the channel. It also checks whether the channel has local clients
2540 on the channel anymore. If it does not have then the channel entry
2541 is removed as it is not needed anymore.
2543 * The silc_server_notify now checks on JOIN notify whether the joining
2544 client is one of locally connected or global. If it is global then
2545 the channel has now global users on the channel and that is marked
2546 to the channel entry. Also, it now saves the global client to
2547 global list who is joining and JOINs it to the channel. This is
2548 for normal server, that is.
2550 Changed silc_server_send_notify_on_channel,
2551 silc_server_packet_relay_to_channel and
2552 silc_server_packet_send_to_channel check if we are normal server
2553 and client has router set (ie. global client) do not send the
2554 message to that client, as it is already routed to our router.
2556 * Implemented LEAVE notify type handling in silc_server_notify
2559 * Tested LEAVE command in router environment successfully. Tested
2560 with two routers, two servers and two clients.
2564 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2566 * Implemented SIGNOFF notify type handling in silc_server_notify
2569 * silc_server_remove_id now removes the client entry from all channels
2570 it has joined and thusly sends SIGNOFF notify type.
2572 * Rewrote the NAMES list generation in server by removing two excess
2573 loops. The lists are created now inside one loop.
2575 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * silc_server_remove_channel_user checks now also global list
2578 for channel and client.
2580 * silc_server_new_channel_user checks now both local and global
2581 list for channel and client. Fixed a bug in client id decoding.
2582 Used to decode wrong buffer.
2584 * silc_server_channel_message checks now both local and global
2585 list for channel entry.
2587 * Tested channel joining (hence JOIN) in router environment
2588 successfully. Tested with two routers, two servers and two
2591 * Tested channel message sending in router environment successfully.
2593 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added silc_server_save_channel_key into server.[ch] to save the
2596 received channel key in Channel Key payload processing. It is
2597 also used in JOIN command reply handling.
2599 Equivalent function silc_client_save_channel_key added into
2600 client.[ch] into client library.
2602 * Changed JOIN command reply to send information whether the channel
2603 was created or not (is existing already) and the channel key
2604 payload. Changed protocol specs accordingly.
2606 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2607 the request was sent by ID and not by nickname. Crashed on
2610 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2613 now correctly save the received data.
2615 * silc_server_free_sock_user_data now notifies routers in the
2616 network about entities leaving the network.
2618 At the same time implemented functions silc_server_remove_id
2619 and silc_server_send_remove_id to receive and send REMOVE_ID
2620 packets. The packet is used to notify routers in the network
2621 about leaving entities. The ID removed will become invalid in
2624 * Added function silc_idlist_del_server into server. Removes and
2625 free's server entry from ID list.
2627 * silc_server_private_message function now checks, if we are router,
2628 that the destination ID really is valid ID, naturally.
2630 * In router when NEW_ID packet is received (for new client) the
2631 hash of the Client ID is saved in the ID Cache but the
2632 client->nickname is set to NULL, instead of putting the hash
2635 IDENTIFY command now also checks that client->nickname must be
2636 valid. If it is not if will request the data from the server who
2637 owns the client. Added new function
2638 silc_server_command_identify_check.
2640 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2641 to set the command to already allocated Command Payload.
2643 * Tested private message sending in router environment with two
2644 routers, two servers and two clients. Fixed minor bugs and now
2647 * Fixed segfault from client's NAMES command. Used to crash if
2650 * Forwarded packets must not be routed even if it is not destined
2651 to the receiver. Changed server code comply with this.
2653 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added `require_reverse_mapping' boolean value to ServerParams
2656 structure. If TRUE (not default) the server will require that
2657 the connecting host has fully qualified domain name.
2659 If the reverse mapping is not required and hostname could not be
2660 found the IP address is used as hostname.
2662 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Implemented version string checking to both client and server.
2665 The check is incomplete currently due to the abnormal version
2666 strings used in development version of SILC.
2668 * Changed all command functions in server to use the new
2671 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Changed char *data to unsigned char *data in ID Cache system to
2674 support binary data as ID Cache data. Changed code to support
2675 binary data in lib/silccore/idcache.c.
2677 * Renamed silc_server_packet_relay_command_reply to
2678 silc_server_command_reply as it is normal packet receiving
2679 function. Rewrote the function to accept command replys for
2680 servers and not only for clients.
2682 * Mark remote router always as registered server if we are connecting
2683 to it. Otherwise, commands sent by the router to us are ignored.
2685 * All ID List find routines now returns the ID Cache Entry pointer
2686 as well if requested.
2688 * WHOIS command works now in router environment, tested with two
2689 routers, two servers and two clients.
2691 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2692 in router environment (as it is almost equivalent to WHOIS) but
2693 hasn't been tested thoroughly. Added new functions:
2695 silc_server_command_identify_parse
2696 silc_server_command_identify_send_reply
2697 silc_server_command_identify_from_client
2698 silc_server_command_identify_from_server
2700 * Disabled route cache adding because adding two different ID's with
2701 same IP replaces the old cache entry thus giving wrong route.
2702 The entry->router->connection is always the fastest route anyway
2703 so route cache may not be needed. Of course, new routes maybe
2704 established after receiving the ID when the entry->router->connection
2705 might not be anymore the most optimal.
2707 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Add route cache for received ID for fast routing.
2711 * Added silc_server_packet_route to route received packet on router
2712 that is not destined to us.
2714 * Renamed silc_server_get_route to silc_server_route_get.
2716 * Added id_string and id_string_len fields into SilcServer to
2717 include encoded ServerID for fast comparing without excess
2718 encoding of the ID's.
2720 * Cleaned up WHOIS command on server side. Added following static
2723 silc_server_command_whois_parse
2724 silc_server_command_whois_check
2725 silc_server_command_whois_send_reply
2726 silc_server_command_whois_from_client
2727 silc_server_command_whois_from_server
2729 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2730 arguments in command replies. All command functions should be
2731 updated to use this macro.
2733 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Minor typo fixes on command reply handling on server.
2737 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added silc_server_command_add_to_channel internal routine to add
2740 the client to the channel after router has created the channel and
2741 sent command reply to the server.
2743 * Added generic silc_server_send_command to send any command from
2746 * Use static buffer with ID rendering instead of duplicating data.
2748 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Fixed a channel user mode bug when joining to a channel server gave
2751 everybody channel founder rights, oops.
2753 * We mark ourselves as the router of the incoming server connection
2754 if we are router ourselves. This way we can check in some packet
2755 sending functions whether it is locally connected server. For
2756 incoming router connections we put NULL.
2758 * For router sending packets locally means now always sending the
2759 packet cell wide; to local clients and local servers. For normal
2760 server sending packet locally means sending it to only local
2763 * Fixed the JOIN command to really work in router environment. If the
2764 channel is created it is always created by the router. Router is
2765 also responsible of making the initial joining to the channel,
2766 sending JOIN notify to the sending server and distributing
2767 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2768 does not exist server doesn't do anything else but forward the
2769 command to the router which performs everything.
2771 * Added silc_server_send_channel_key function to send the Channel Key
2774 * Added silc_server_create_channel_key to create new channel key. The
2775 channel key is now re-generated everytime someone joins or leaves
2776 a channel, as protocol dictates. Note: channel->key_len is the
2779 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2782 packet_receive.[ch] to separate packet sending and receiving
2783 routines. The server.[ch] now includes everything else including
2784 actual packet processing (writing and reading data) and other
2787 Renamed silc_server_private_message_send_internal to
2788 silc_server_send_private_message. The routine is still though
2789 used only to relay private messages as server does not send
2790 private messages itself.
2792 Renamed silc_server_new_channel to silc_server_create_new_channel
2793 and added new function sicl_server_new_channel that handles the
2794 incoming New Channel packet. Added also new sending function
2795 silc_server_send_new_channel to send New Channel Payload.
2797 * Added new function silc_server_notify to process incoming notify
2798 packet to the server/router. Server may then relay the notify
2799 to clients if needed.
2801 * Added new function silc_server_new_channel_user to process incoming
2802 New Channel User packet. Router will redistribute the packet and
2803 send JOIN notify to its local clients and locally connected servers
2804 if needed. Normal server will send JOIN notify to its local client
2805 on same channel when received this packet. Added also corresponding
2806 sending function silc_server_send_new_channel_user to sent the
2809 * Added boolean route argument to send_notif_to_channel and
2810 packet_send_to_channel functions to attempt to route the packet
2811 if it is TRUE and send only locally if it is FALSE.
2813 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2815 * silc_server_replace_id now broadcasts the received replace ID
2816 packet if it is not broadcast packet already. The router must
2817 broadcast to inform other routers about changed ID.
2819 * Added backpointer to server's router into SilcServer context in
2820 silcd/server_internal.h.
2822 * Fixed silc_server_packet_broadcast to send correct broadcast
2825 * The channel key is now distributed to the local client as soon
2826 as it is received from the router (in router environment) so that
2827 no other packet may be sent for the channel until client has
2830 * silc_server_remove_channel_user now broadcasts the received
2831 Remove Channel User packet if it is not broadcast packet already.
2832 The router must broadcast to inform other routers about removed
2835 * Added users field into SilcPacketContext that is a reference count
2836 of the context. One can increase the reference count by calling
2837 silc_packet_context_dup which is now changed to just increase the
2838 reference count instead of duplicating the data. The reference
2839 count is decresed by calling silc_packet_context_free that will
2840 free the data after the reference count hits zero.
2842 For now on the packet context and everything allocated into it
2843 (including the raw packet from network) must be freed by calling
2844 the new silc_packet_context_free function. Added also new function
2845 silc_packet_context_alloc that must be used now to allocate the
2846 context. This also means that if a routine is asynchronous from
2847 silc_[client/server]_packet_parse_type the packet context must
2848 be duplicated by calling silc_packet_context_dup. Otherwise it
2849 gets free'd after silc_[client/server]_packet_parse_type returns.
2850 Also, one must remember that if packet is duplicated then its
2851 reference count must be decresed by calling the free function as
2852 many times as it was duplicated.
2854 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2855 from both client and server.
2857 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Made joining to a channel working in router environment.
2861 * Cleaned up JOIN command on server side and create function
2862 silc_server_command_join_channel internal routine to make the
2865 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Changed silc_command_pending list to SilcDList. Also, added
2868 `ident' field to SilcServerCommandPending structure to identify
2869 the reply and to call correct callback.
2871 Added silc_server_command_pending_check function to replace the
2872 corresnponding macro. The silc_command_pending list is not
2875 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2876 to set identifier to previously allocated Command Payload. It
2877 is used to set identifier for command when resending Command
2880 * Added silc_command_payload_encode_payload to encode Command
2881 Payload buffer from SilcCommandPayload structure.
2883 * Added silc_argument_payload_encode_payload to encode Argument
2884 payload buffer from SilcArgumentPayload structure.
2886 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Changed WHOIS command to support router connection on server side.
2889 The whois request is always sent to router unless the server is
2890 standalone server. After server has received the reply from the
2891 router will it send the reply to the client.
2893 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2894 broadcast received broadcast packet. The function is used only
2895 by router. The broadcast packet is always sent to the router's
2898 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2899 render given ID to printable string, for log files for example.
2901 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Made basic router to router connections working. At least they
2904 can now connect to each other but nothing really works the way
2905 they are supposed - yet.
2907 * Added new initiator token to RouterConnection configuration
2908 file in silcd/serverconfig.[ch]. It is used to tell whether we
2909 are the initiator to the remote router or whether we'll expect
2910 the other end to connect.
2912 * Moved registering of listener task to silc_server_init, hence
2913 the server starts listenning as soon as it is run, even if it
2914 does not have connections to other routers. Let's see how well
2917 * Changed default connection retry timeouts for more suitable in
2920 * Removed cipher and such arguments from silc_idlist_add_client
2921 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2922 Added new function silc_idlist_add_data to add the keys and stuff
2925 * Added SilcIDListData structure and added it to SilcClientEntry
2926 and SilcServerEntry as their first field in the structure. This
2927 way we can explicitly cast the ID entries to the SilcIDListData
2928 structure and get common data for the entries. In past, we had
2929 to first check what type of connection it is and then cast it to
2930 correct ID entry type. Now, we can directly cast the opaque
2931 pointer to the SilcIDListData (no matter what ID entry it actually
2932 is) and get the data needed.
2934 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2937 in some circumstances even if threre were timeout tasks, though not
2938 IO tasks, but tasks anyway. Now fixed.
2940 * Defined SilcServerConnection structure to hold connection specific
2941 stuff about directly connected servers and routers. The definition
2942 is currently in silcd/server_internal.h. I thought about having
2943 a bit more important role fro this struct but for now it is used
2944 only when connecting to other server (or router actually).
2946 * Added connecting retry support in server when connecting to
2947 router(s). The retry feature implement exponential backoff
2948 algorithm. Also, added SilcServerParams structure to hold default
2949 parameters for server. For now, it include these retry settings
2950 and are hard coded. After server is moded to be as Silc Server
2951 Library this structure will be more important.
2953 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2955 * Changed client librarys channel->clients table to SilcList and
2956 changed code accordingly.
2958 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Changed client's channel table to SilcList and changed code
2961 accordingly. Also changed SilcChannelClientEntry to include back-
2962 pointer to the channel so that client entry can use that structure
2963 as list as well and we have fast cross-reference to the channel.
2964 This change dramatically decreased the complexity of channel
2965 handling with client entry and vice versa (removed one extra
2966 loop when searching for channel entry from many functions).
2968 * Changed server->sim from table to SilcDList and changed code
2971 * NAMES command can now be used from user interface. It will show
2972 the user list on the channel, neatly.
2974 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2975 Code now saves realname of the user if it becomes available.
2977 * Renamed configure.in to configure.in.pre and made ./prepare
2978 script to automatically add correct version string to
2979 configure.in which it creates from configure.in.pre.
2981 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * NAMES command reply now shows users mode with the nickname when
2986 * Moved silc_client_ch[u]mode[_char] functions from
2987 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2988 place sucks, they are utility functions and should be in some
2991 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2993 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2996 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Added TRQ (efficient deque and list library) into lib/trq. This is
3001 a very good list library that is currently used in the SILC. Defined
3002 SilcList API over the library because I didn't like the API very
3003 much. See lib/trq/silclist.h for the API and examples of how to
3004 use the API. Fixed various places in the code to use the new
3005 SilcList API. The SilcList is meant for lists that has a structure
3006 already defined as a list. It is not suitable to add just some
3007 context to the list (in TRQ, the context is the list actually).
3009 So, I defined SilcDList that can be used for the purpose where
3010 predefined list structure does not exit. This can be used as
3011 such list. Now some context just can be added to the SilcDList.
3012 Currently this list is not used in the SILC just yet, though there
3013 are a lot places where this can replace dynamically allocated
3014 tables and I will fix these places, later, to use SilcDList.
3015 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3016 and use TRQ internally).
3018 Also fixed some annoying warning messages that the original TRQ
3019 code generated. Also minor changes to TRQ's Makefile.in.
3021 * Added support for querying by Client ID to both WHOIS and
3022 IDENTIFY commands into server, as required by the protocol.
3024 * Removed method function pointers from SilcBuffer structure. They
3025 weren't used to anything and just increased the context size for
3026 no good reason. This change also made silc_buffer_alloc and
3027 silc_buffer_free functions inline functions.
3029 * Disabled command flooding detection support until it's fixed so
3030 that it accepts commands in but does not execute them more than once
3033 * Added silc_net_localhost(), to return local hostname, into
3034 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3035 that must be initialized before calling silc_client_init.
3037 * Added new function: silc_server_send_notify_on_channels to send
3038 notify messages to all channels client has joined. It is assured
3039 that the message is sent only once per client.
3041 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3042 lib/silcutil/silcutil.[ch] as silc_format function. The new
3043 function is generic and is used by server as well, not only by
3044 the logging routines.
3046 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3047 the provided version string was not acceptable. Added new function:
3048 silc_ske_check_version into lib/silcske/silcske.h. The function
3049 must be implemented by the application (client or server) and it
3050 does not reside in the SKE library. The function checks the version
3051 string remote end sent.
3053 * Added back pointers (to opaque context and to SilcSocketConnection)
3054 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3056 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3057 duplicate packet context structure.
3059 * Changed `notify' client operation to send same arguments as client
3060 receives from server except for ID's. ID's are mapped to correct
3061 ID entry and that is returned. Also, if channel entry is not sent
3062 by server but the notify is for channel the channel entry is sent
3063 to application (otherwise application doesn't know that it is for
3064 channel (library gets it from packet's Destination ID)).
3066 * Added silc_client_remove_from_channels into client library to
3067 remove a client from all channels it has joined to. Used when
3068 received SIGNOFF notify from server. Added also new function
3069 silc_client_replace_from_channels to replace old ID entry with
3070 new ID entry on all channels. Used when received NICK_CHANGE
3073 * Fixed ID Cache list handling in silc_idlist_get_client in
3074 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3075 to get (or query) client by ID.
3077 * Updated TODO list.
3079 * Added connection authentication status message defined by the
3080 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3081 support for these into the code in client and server side.
3083 * Added generic function silc_client_send_command to send any command
3084 with variable argument list. Application should use this function
3085 to send commands if the command functions provided by the library
3086 does not suite for the application's user interface needs.
3088 * Added new `failure' client operation. Application is notified about
3089 received failure packet if client is executing a protocol. In this
3090 case the protocol's execution has failed.
3092 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3093 is required by the protocol.
3095 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3096 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3099 * Added status flag to SilcSKE object to indicate realtime status
3100 of the SKE protocol.
3102 * Application receives now exactly same command reply arguments as
3103 the library receives from server. However, if ID is received the
3104 corresponding ID entry is returned to the application (eg. Client
3105 ID is mapped to correct SilcClientEntry entry and that is returned).
3106 Changed command_reply client operation due to this change.
3108 * Changed all ID's in commands and in command replys as ID Payloads.
3109 Change affected both client and server side codes.
3111 All ID's sent in SILC network (with execption of ID's in SILC
3112 Packet header) are sent in ID Payload to support variable length
3115 * Server now notifies nick changes and notifies all clients on
3116 the channels about the new nickname (about the new Client ID,
3119 * Implemented CMODE command to change channel modes. Supports all
3120 channel modes defined by the protocol specs except ban and invite
3121 lists. (Also, private channel key mode is supported but support for
3122 setting private channel key in client is missing, thus, this mode
3123 has no effect on client side (except that server requires that the
3124 client uses private channel key and normal channel traffic does not
3127 Also, invite mode works per se, but INVITE command does not work
3128 yet correctly, so you can set channel as invite only channel but
3129 inviting clients to the channel does not work (it is yet to be
3130 thought what's the best way to do it).
3132 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3133 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3134 Implemented CUMODE command to change user's mode on the channel.
3135 Supports all modes defined by the protocol specs.
3137 * Added NAMES command reply to return users modes on the channel.
3139 * Removed unnecessary and slow ciphers from lib/silccrypt.
3141 * Set SO_KEEPALIVE option to connection sockets by default.
3143 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3145 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3146 redefined the Notify Payload into protocol specs.
3148 * Added silc_id_payload_parse_id to get ID directly from raw
3151 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3154 accept searching by Client ID as well.
3156 * Added support for LEAVE and SIGNOFF notify types in client library.
3158 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3159 to parse ID Payload from raw data.
3161 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Added flags parameter into silc_ske_assemble_security_properties
3164 function in lib/silcske/silcske.[ch].
3166 * Changed notify client operation to fit better for notify messages
3167 sent by server. The notify payload received from server is now
3168 passed to the application (after parsing it to SilcNotifyPayload).
3169 It is application's responsibility to retrieve the arguments
3170 from the payload and show the message the way it wants. The message
3171 sent by server is implementation specific.
3173 * Changed public keys to comply with the protocol specification.
3174 Old public keys are not supported anymore and are not compatible.
3176 * Removed nickname from Channel Payload as the latest draft removed
3177 it. The client must resolve the nickname from the NAMES command
3178 reply received when it joined the channel.
3180 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3182 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Fixed some errors in protocol specification drafts.
3186 * Created lib/silccore/silcnotify.c to implement Notify Payload
3187 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3188 generic payloads described by protocol specifications. The file
3189 includes implementations for ID Payload and Argument Payload.
3191 * Changed Command Payload implementation to use the new Argument
3192 Payload. Changed command_xxxx_payload to command_payload_xxxx
3193 to comply with SILC coding conventions.
3195 * Added suppport for Argument Payload handling in Notify Payload
3196 implementation as protocol requires it. Added the new support
3197 into server and client lib as well.
3199 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Added support for multiple nicknames on same channel. [n] is
3202 added locally to the nickname if there are more than one same
3203 nicknames on the channel.
3205 * Server now sends all nicknames that matched WHOIS request.
3206 Client also shows the list received from server.
3208 * Added TOPIC command to client side. User can now set and show
3209 current topic on channel.
3211 * Added MOTD command to client and server. Also, server sends the
3212 motd when client connects to the server.
3214 * Changed version strings to comply ISO 8601.
3216 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Fixed protocol error handling in client library. It should now
3219 cope even if the SKE fails for some reason.
3221 * Made new protocol specification drafts for submitting to IETF.
3223 * Implemented TOPIC command to server in silcd/command.c.
3225 * Added two new notify types into lib/silccore/silcnotify.h:
3226 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3227 notify nickname change and topic setting/change on a channel.
3229 * API change of command_reply operation in client library. The
3230 application gets now the status type received from server as well.
3232 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3236 * Cras fixed and optimized the packet handling even further and
3237 it should work now. Minor change to the prototype of function
3238 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3240 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Added new function into lib/silcutil/silcschedule.[ch]:
3243 silc_schedule_with_fd to select() a specified fd. The function
3244 returns after timeout expires or data arrives or goes. The
3245 function is used by packet routines to wait that all data is
3246 received from network.
3248 * Fixed data reading from network in lib/silccore/silcpacket.c.
3249 The code now assures that all data is read from the fd and then
3250 continues packet processing. This was a bug fix since the code
3251 used to drop some data in some circumstances.
3253 * Added new function into lib/silcclient/client.[ch]:
3254 silc_client_start_key_exchange to start key exchange after
3255 connection has been established to server. The code internally
3256 now uses this funtion but its main purpose was to provide it
3257 for applications that perform their own connecting. After
3258 application has created a connection it merely calls this
3259 function to start the key exchange between client and server.
3260 The library takes care of everything else after that.
3262 Updated also lib/silcclient/README to explain the usage of
3265 * Do not send to application information that connection has
3266 been established. Application gets notified it by connect
3269 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Applied cras's patch to add silc_schedule_one function. The
3272 function runs scheduler once and returns.
3274 * Fixed the scheduler after cras messed it up. The timeout
3275 handling works now as it's supposed to work.
3277 * Added into lib/silccore/ silcnotify.h to include notify
3278 message types support. Changed silc_server_send_notify*
3279 functions, in server.[ch], to support those new notify types.
3280 Added the support for the notify types into client library,
3281 as well. Added new notify client operation into ops.h in
3284 * Changed silc_server_packet_send_to_channel to send normal
3285 packets instead of just channel message packets. The function
3286 is now used to send the notify packets to channels. It is not
3287 used to send channel message packets anymore, as server never
3290 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3291 va_arg()s as it seems to require it nowadays. I guess, if SILC
3292 is compiled with older va_arg() the new code should work anyway.
3294 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Splitted core library. Core library (lib/silccore) includes
3297 now only SILC protocol specific core (and common) components.
3298 Created new utility library (lib/silcutil) that includes more
3299 generic purpose stuff. The stuff for util library was taken
3300 from the old core library. This was minor and easy split.
3302 * Created SILC Client Library (lib/silcclient) that includes
3303 implementation of the SILC client without user interface. This
3304 was major move from silc/ directory. The code has been changed
3305 so that it is transparent towards the user interface. The
3306 silc/ directory includes now the same user interface as before
3307 and it uses the new client library. Read lib/silcclient/README.
3308 Basicly, the client library performs everything else related
3309 to SILC except user interface handling. Also, configuration
3310 files are considered to be part of user interface and library
3311 does not handle them.
3313 This change also changed a lot of structures, function naming etc.
3314 Most important change was that SilcClientWindow object was
3315 renamed to SilcClientConnection in the client library. Created
3316 also new file lib/silcclient/ops.h. Also added new files
3317 silc/local_command.[ch] and silc/client_ops.[ch].
3319 All these changes were made to make it easier for user interface
3320 designers to create what ever user interface for the SILC client
3323 It is also expected that the server will be moved to lib
3324 directory as well and SILC Server Library will be created;
3325 sometimes in the future.
3327 * Removed Local commands from lib/silccore/silccommand.h as
3328 they are application specific and new client library does not
3329 handle any of those anymore.
3331 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3332 old client implementation in silc/.
3334 * Added support for callback functions in SILC_LOG_* macros.
3335 Application can now set its own callbacks that will be called
3336 instead of using the default functions that will always print
3337 the debug messages to stderr (or stdout). Also, debugging can
3338 now be disabled by setting silc_debug to FALSE and re-enabled by
3339 setting it to TRUE. Note, that logging will still work even
3340 if debugging is disabled.
3342 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3343 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3344 silc_log_reset_debug_callbacks.
3346 * To enable debugging in silc client one must give now -d
3347 option on command line.
3349 * Changed silc_schedule_init to automatically allocate task queues
3350 if they are not allocated before calling it.
3352 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Added GMP 3.1 into math library.
3356 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3359 a channel in SILC network. The packet is used by servers and
3360 routers to notify other routers that user has left a channel.
3361 This little feature was missing until now. Added the feature
3362 to protocol specification as well.
3364 Added functions: silc_server_send_remove_channel_user and
3365 silc_server_remove_channel_user into server.[ch].
3367 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3368 lib/silccore/silcpacket.h. However, they are not implemented
3371 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Fixed joining to a channel and sending channel messages
3374 between server and router. The channel message sending should
3375 now work inside a cell.
3377 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Fixed the private message sending between server and router.
3380 The private message sending should now work inside a cell.
3382 * Added silc_server_replace_id into server.[ch] to replace
3383 existing ID in the SILC network.
3385 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3386 and silc_idlist_replace_server_id into idlist.[ch] in server.
3388 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Fixed the server to server connections. Server can again now
3391 connect to router. Router to router connections probably does
3394 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Added dynamic protocol registering support. Now protocols can
3397 registered and unregistered on the fly. Patch by cras.
3399 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Added lib/contrib directory to hold routines that some platforms
3402 don't have but are needed by SILC.
3404 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3405 into lin/contrib to provide getopt() and getopt_long() for
3406 those who don't have it.
3408 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added AWAY command to client. When away message is set and
3411 client receives a private message packet the client automatically
3412 replies to the sender with the away message.
3414 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3415 bug seemed to be the cause of recent problems when compiling
3418 * Added version detection support to SKE protocol specification
3419 and added the new changes to the SKE implementation as well.
3420 There were other minor changes in the SKE protocol as well.
3422 Many changes in lib/silcske/silcske.[ch] and in
3423 lib/silcske/payload.[ch].
3425 * Added ^U functionality, clear input line. Patch from cras.
3427 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Mainly small bugfixes on core library. Fixed some debugging
3430 logging and buffer overflow in silclog.c.
3432 * Updated config.sub and config.guess on the distribution tree.
3434 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added command lagging support in server. Client may execute
3437 commands now only once in two seconds.
3439 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Optimized packet reception. MAC computation and checking is now
3442 also more optimized. A lot previously duplicated code is now
3443 used as generic by both client and server.
3445 * Fixed key pair generation in clientutil.c
3447 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added into lib/silccore/silcbufutil.[ch] new function;
3450 silc_buffer_realloc.
3452 * Moved generic packet sending/encryption functions to
3453 lib/silccore/silcpacket.[ch] from client and server. Some
3454 rewriting of the functions.
3456 * Moved all generic packet reception/decryption functions to
3457 lib/silccore/silcpacket.[ch] from client and server. The
3458 packet processing is now much cleaner in both client and server.
3459 These were major changes in both client and server.
3461 * Created many common functions in server to do packet sending.
3462 Previously code were duplicated a lot, this has been removed
3465 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Rewrote major parts of the ID cache system. Don't know
3468 whether it is better now or not but at least the API is more
3471 * Major rewrite on ID cache stuff on client because of the ID
3472 cache API changes. Added idlist.c to client.
3474 * Also major rewrite on ID cache stuff on server as well.
3475 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3476 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3477 in hand, instead they are all put into the ID cache system now.
3478 All server_idlist_* routines uses ID cache now instead of
3479 traversing its own lists (those lists does not exist anymore).
3480 SilcIDList though still exists. Also, SilcXXXEntry's are
3483 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Finally made the SKE implementation compliant to the protocol
3486 specification. All mp integers are now binary encoded as
3487 opposed being HEX encoded.
3489 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3492 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3493 functions: silc_[encode/decode]_pem. Also added function
3494 silc_encode_pem_file to PEM encode with newlines ('\n') for
3497 * SILC public keys are now encoded either PEM or binary. Same
3498 option is for private keys as well. By default private keys
3499 are binary encoded and public keys PEM encoded. Silly HEX
3500 encoding were removed.
3502 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3503 function to create fingerprints.
3505 * Fixed a bug in SHA1; does not change the original data anymore.
3507 * Partly implemented INFO command on client and server side.
3508 Fixed CLEAR command. Changes to SERVER command; show current
3509 server(s) when giving command without arguments. Added
3510 VERSION command to client.
3512 * Added check to server that unregistered connections cannot
3513 execute commands (unless it is specificly allowed).
3515 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Fixed screen refresh.
3519 * Fixed channel joining bug from client. On some circumstances
3520 client tried to join to a channel it had already joined.
3522 * Added public key verification process into client's protocol.c.
3523 The client now verifies the public key from user and saves
3524 it into ~./silc/serverkeys/ directory.
3526 Added into: clientutil.[ch]: silc_client_verify_server_key.
3528 * Changed SKE protocol's silc_ske_initiator_finish function
3529 to accept callback function that verifies the received public
3530 key. Removed old silc_ske_verify_public_key function.
3532 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3535 silc_pkcs_private_key[_data]_set.
3537 * Made the password and public authentication more cleaner in
3538 server's protocol.c.
3540 * Removed historic and obsolete protocol `channel_auth' from
3541 both client and server.
3543 * Removed wrong way of sending command status messages from
3544 server to client in server's command.c. The old way violated
3545 protocol specification.
3547 Changes to silccore/silccommand.[ch]: removed
3548 silc_command_encode_status_payload -> not needed anymore,
3549 changed silc_command_encode_payload_va to accept extra
3550 argument on variable argument list. The argument type must
3551 now be provided to the function. Also, added new function:
3552 silc_command_encode_reply_payload_va which is same as
3553 normal command_encode_payload_va except command status type
3554 is provided as extra argument.
3556 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Added ~./silc directory handling. The directory includes the
3559 public and private keys for the client.
3561 Added silc_client_check_silc_dir, silc_client_create_identifier
3562 and silc_client_load_keys.
3564 * Implemented SILC protocol compliant public key. Added public
3565 and private key saving to and loading from files.
3567 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3568 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3569 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3570 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3571 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3573 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3574 silc_pkcs_load_[public/private]_key.
3576 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Added silc_server_get_route (route.[ch]) to get connection
3579 data for the fastest route for given ID.
3581 * Implemented INVITE command on client and server. The command
3582 were re-defined in the SILC Protocol Specification and the
3583 implementation now complies with the specification.
3585 * Implemented PING command on client and server.
3587 * Implemented NAMES command on client and server. The server side
3588 supports currently only normal server not router server yet.
3589 Some changes to NAMES definition in SILC protocol specification.
3591 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Implemented LEAVE command on client and server.
3595 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3596 again. This change was made to the protocol as well. Server
3597 should not violate the protocol specification anymore.
3599 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3602 was tested. SOCKS4 was not but should work anyway.
